Abstract: A display device includes a base substrate including: a display region including a pixel, and a pad region defining an end surface of the base substrate which is furthest from the display region and exposed outside the display panel; an insulating layer in the display region and the pad region; and in the pad region: a signal pad electrically connected to the pixel and to a dummy pad; the insulating layer covering the signal pad and the dummy pad and defining an end surface of the insulating layer which is furthest from the display region and exposed outside the display panel; and a first opening in the insulating layer which exposes the signal pad outside the insulating layer and outside the display panel. In the pad region, the end surfaces of the base substrate and the insulating layer together define an inclined edge of the display panel.

Abstract: A display apparatus includes a display area extending in a first direction and a second direction, first to fourth sub-pixels, and a spacer. The first sub-pixel emits a first color light, and includes first and second sides extending in a third direction inclined at a predetermined angle with the first direction, and third and fourth sides extending in a fourth direction perpendicular to the third direction. The second sub-pixel emits a second color light, and is disposed adjacent to the second side of the first sub-pixel in the fourth direction. The third sub-pixel emits a third color light, and is disposed adjacent to the fourth side of the first sub-pixel in the third direction. The fourth sub-pixel emits the first color light, and is disposed adjacent to the second and third sub-pixels. The spacer is disposed between the first and second sub-pixels and between the third and fourth sub-pixels.
