Abstract: A display apparatus includes a central area arranged at a center of a substrate, and a corner area arranged at a corner of the central area. The corner area includes a central corner area including a plurality of extension areas extending in a direction away from the central area and a first adjacent corner area and a second adjacent corner area respectively arranged at opposite sides of the central corner area. The plurality of extension areas is spaced apart from each other by a spaced area in which the substrate is arranged, and the central corner area and the first adjacent corner area are spaced apart from each other by a first penetration area in which the substrate is not arranged, and the central corner area and the second adjacent corner area are spaced apart from each other by a second penetration area in which the substrate is not arranged.

Abstract: A display apparatus includes: a substrate including a first surface, a second surface opposite the first surface, a display area defined on the first surface, and a non-display area defined on the second surface; a plurality of display elements at the display area on the first surface of the substrate; a driving circuit on the second surface and overlapping with the display area of the substrate; a first conductive pattern on the second surface of the substrate; and a second conductive pattern on the first surface of the substrate and connected to the first conductive pattern via a contact hole extending through the substrate. A surface roughness of the second surface of the substrate is greater than a surface roughness of the first surface of the substrate.

Abstract: The present disclosure relates to a display panel and a display apparatus. The display panel includes: a substrate including a main display area and a corner display area extending from a corner of the main display area; and a plurality of pixels arranged in the main display area and the corner display area. The substrate further includes: a first base layer; a first barrier layer arranged on the first base layer; and a second base layer arranged on the first barrier layer. A thickness of the substrate in the corner display area decreases away from the main display area.

Abstract: A display apparatus includes a cover window including a window central area, a first window area connected to the window central area in a first direction, a second window area connected to the window central area in a second direction, and a window corner area contacting a corner of the window central area, and a display panel arranged below the cover window. When a radius of curvature of a portion of the display panel arranged to overlap the first window area is RB, and a length of the portion of the display panel arranged to overlap the first window area in a direction perpendicular to a portion of the display panel arranged to overlap the window central area is Z0, a first width (WP1) of the portion of the display panel in the first direction and arranged to overlap the first window area, satisfies the following equation:
