摘要： The displacement between a TFT substrate and a counter substrate and the cut of an alignment film caused by a columnar spacer are prevented. A liquid crystal display device includes: a TFT substrate including a scanning line extending in a first direction, a picture signal line extending in a second direction, a pixel electrode formed in a region surrounded by the scanning line and the picture signal line, and a common electrode formed as opposed to the pixel electrode through an insulating film; a counter substrate disposed as opposed to the TFT substrate and having a spacer; and a liquid crystal sandwiched between the substrates. A common metal interconnection is formed to cover the picture signal line or the scanning line, and stacked on the common electrode. A through hole is formed on the common metal interconnection. The tip end of the spacer is disposed inside the through hole.

摘要： A display device substrate includes a transparent substrate arranged in parallel with a face on which an image is displayed and a light-shielding film partially formed on the transparent substrate for shielding light. The light-shielding film has, at a portion of the transparent substrate along an edge thereof on at least one side, a low light-shielding portion having a lower light-shielding capability. The low light-shielding portion is formed with a smaller thickness than that of the other portion in the light-shielding film. With this configuration, even when, in a gang printing display panel in which a plurality of display panels each having the display device substrate are arranged, the light-shielding films of the display panels adjacent to each other are formed continuously, cutting can be performed more easily at a position to be cut.

摘要： A display device includes a first substrate which is light transmissive and has a display region and a periphery region surrounding the display region. A light shielding portion is formed in at least the periphery region of the first substrate and has a light passing portion in the periphery region. A first scale mark portion is formed on the first substrate so as to be arranged inside the light passing portion. A second substrate overlaps the first substrate and a second scale mark portion is formed on the second substrate and forms a pair with the first scale mark portion. A sealing member seals the first and second substrates in the periphery region between the display region and the light passing portion. A dam portion is formed on the first substrate between the display region and the light passing portion.

摘要： A liquid crystal display device having 2-pixel multi-domain type pixels, in which columnar spacers are disposed in optimal positions. Each of plural video lines has a first portion in which an acute-angled crossing angle of two crossing angles crossing each of scanning lines becomes a positive angle in a clockwise direction from each of the scanning lines, and a second portion in which an acute-angled crossing angle of the two crossing angles crossing each of scanning lines becomes a negative angle in the clockwise direction from each of the scanning lines. The first and second portions are alternately disposed so as to hold the scanning line between them.

摘要： Red pixels (R), blue pixels (B) and green pixels (G) are formed in parallel. First columnar spacers 10 and second columnar spacers 20 are formed on a first substrate. The distance between the first substrate and a second substrate in a normal state is determined by the first columnar spacers 10. The diameter of a light blocking film corresponding to each first columnar spacer 10 is greater than the diameter of a light blocking film corresponding to each second columnar spacer 20. The first columnar spacer 10 is not formed at a boundary between a green pixel (G) and a red pixel (R) or a boundary between a green pixel (G) and a blue pixel (B). The second columnar spacer 20 is formed at a boundary between pixels irrespective of the pixel color. Thus, appropriate color balance can be attained with ease without having a drop in the luminance.
