An image display device includes a cathode ray tube. The cathode ray tube includes a panel with an inner phosphor screen, and a funnel connected to the panel with a cone portion mounting a deflection unit on the outer circumference thereof. A neck is connected to the funnel while mounting an electron gun therein. The interface between the cone portion and the neck is called a neck seal line, and the portion of the electron gun sealed to the neck called a gun sealing portion. When the distance between the panel and the neck seal line is indicated by A and the distance between the neck seal line and the gun sealing portion by B, the values of A and B satisfy the following conditions: 0.31

A flat panel for a cathode ray tube includes a faceplate portion, a skirt portion and a blend round portion joining the faceplate portion with the skirt portion. A point where an external contour of the faceplate portion meets an external blend round contour of the blend round portion is defined as a first point and a point where an external contour of the skirt portion meets the external blend round contour is defined as a second point. The external blend round contour is formed between an imaginary arc whose end points coincide with the first and second points and a line segment whose end points coincide with the first and second points, or is the line segment. The imaginary arc is smoothly connected to the external contours of the faceplate portion and the skirt portion at the first and the second point.

A button structure for displaying a multi-layered appearance includes a first flexible body, a film layer, a first color layer, a second flexible body, a second color layer, and a third color layer. The film layer is disposed on a top surface of the first flexible body. The first color layer is disposed between the first flexible body and the film layer. The second flexible body is disposed on a top surface of the film layer. The second color layer is disposed between the second flexible body and the film layer. The third color layer is disposed on a top surface of the second flexible body. Hence, the above-mentioned layers are integratedly formed together to display a multi-layered appearance.

A radius of curvature of an arc passing through three points on an outer surface of a panel, which respectively correspond to a pair of diagonal axis ends on one diagonal axis of a phosphor screen and a center of the phosphor screen, is 10,000 mm or more. A shadow mask is made of an aluminum killed material. Assuming that a thickness of the panel is Td at the diagonal axis end of the phosphor screen, Tmd at an intermediate point between the diagonal axis end and the center, Th at a major axis end of the phosphor screen, and Tmh at an intermediate point between the major axis end and the center, 0.5 ≦Tmd/Td≦0.62, and 0.65≦Tmh/Th≦0.80 are satisfied. Because of this, an inexpensive color picture tube can be provided, in which the visibility is excellent, the degradation in color purity caused by doming is suppressed, and the formability of the shadow mask is enhanced.

An envelope of an image display device has a front substrate and a rear substrate opposed to the front substrate, and respective peripheral edge portions of the front substrate and the rear substrate are sealed together with a sealing layer which contains an electrically conductive sealing material. An electrode for energizing the sealing layer is attached to the envelope. The electrode is formed of an electrically conductive member, is in electrical contact with the sealing layer, and has a conduction portion exposed to the outside.

A cathode ray tube has a vacuum envelope including a panel portion having a phosphor screen, a neck portion having a stem fused and sealed to one end thereof, and a funnel portion for connecting the other end of the neck portion and the panel portion. The stem includes plural stem pins annularly arrayed, sealed thereto and extending therethrough for supporting an electron gun in the neck portion. An outside diameter of the neck portion in a region thereof facing a major portion of the electron gun is not more than 29.1 mm. A stem mound is raised and formed integrally with the stem around a base of each of the stem pins on an electron-gun-supporting side thereof. A first distance R1 and a second distance R2 satisfy a relationship, 0

A flat panel display (500 or 700) contains a faceplate structure (510 or720), a backplate structure (511 or 730) coupled to the faceplate structure, and a plurality of spacers (501-503, 601, or 701-707) situated between the faceplate and backplate structures. The faceplate structure is formed with a faceplate )721) and a light emitting structure (722). The backplate structure is formed with a backplate (731) and an electron emitting structure (732). The core of each spacer is a spacer body (602 or 757). A face electrode (501a-503a, 203, 604, or 771-778) overlies the spacer body of each spacer. A common bus structure (504 or 723) electrically connects the face electrodes, thereby enabling charge built up on any particular spacer to be distributed among all the spacers.

The display screen (11) is made of pixels (P) connected to one edge (11a) of the screen by wires (12) separated by a given pitch (s) so as to be controlled by respective terminals (18) of integrated circuits (16) outside the screen. The terminals (18) of each integrated circuit are disposed in a plurality of parallel rows (19) in which they are separated from one another by a pitch (Sm) equal to several times the pitch of the wires. Each integrated circuit is mounted on a connecting support (10) formed by an insulating film (21) carrying conductive tracks (23) connecting the terminals of the integrated circuit to the corresponding wires of the screen, the tracks extending substantially at the pitch of the wires. The mounting is done simply by collective reflow of bumps between the tracks (23) and the terminals (18), and the support (10) makes it possible to test the integrated circuits before they are mounted on the screen.
