摘要： A display apparatus includes: a display panel; an enclosure enclosing the display panel; a cover member covering a front surface of the display panel; an actuator connected to the cover member and having a function of applying vibration to the cover member; and a viscous body arranged between the display panel and the cover member. The viscous body is bonded to the display panel and the cover member, and, when a periodic stress having a vibration frequency of ½ period per second is applied to the viscous body, a dynamic elastic modulus of the viscous body is equal to or lower than 1×10−3 of Young's modulus of the viscous body.

摘要： According to one embodiment, a display device includes a display area with pixels, and a detection electrode which includes first conductive lines overlapping the display area. Each of the pixels includes a first subpixel, a second subpixel adjacent to the first subpixel in a first direction, a third subpixel adjacent to the first subpixel in a second direction, and a fourth subpixel adjacent to the third subpixel in the first direction and to the second subpixel in the second direction. The pixels are arranged in the first direction with a first pitch, and the first conductive lines are arranged in the first direction with a second pitch which falls within a range of 2.2 times the first pitch or more and 3.2 times the first pitch or less.

摘要： In a display device, light emitting areas and colored areas each have a predetermined planar shape having no rotational symmetry so that rotation of the area by an angle greater than or equal to 0° but smaller than 360° does not produce an initial shape of the area and are so arranged as to have different types of rotation angle. The colored areas are grouped based on a set of the colored areas of colors different from one another to forma plurality of full-color pixels. The full-color pixels are so arranged that the rotation angle of the colored areas of the same color have different types. In the full-color pixels of the same type, the colored areas of the same color have the same rotation angle. In the full-color pixels of different types, the colored areas of the same color have different rotation angles.
