Abstract

A display panel includes: a substrate including a front display area, where a first display element is in the front display area, a first side display area connected in a first direction to the front display area, a second side display area connected in a second direction to the front display area, a corner display area between the first side display area and the second side display area, where a second display element is in the corner display area, an intermediate display area located between the front display area and the corner display area, where a third display element is in the intermediate display area, and a groove is defined on the substrate; and an inorganic pattern layer on opposing sides of the groove and including a pair of protruding tips protruding toward a center of the groove, where the groove is between the second and third display elements.

Claims (24)

1 . A display apparatus comprising:

a display panel comprising a front display area, a corner display area at a side of a corner of the front display area to be bent, and an intermediate display area between the front display area and the corner display area, wherein a first display element is in the front display area, a second display element is in the corner display area, and a third display element is in the intermediate display area; and

a cover window covering the display panel,

wherein the corner display area comprises:

pixel arrangement areas in each of which the second display element is, and

connection areas for connecting the pixel arrangement areas to the intermediate display area,

wherein adjacent pixel arrangement areas and adjacent connection areas define a through-area,

wherein a connection wiring extending from the intermediate display area to the pixel arrangement areas is in the connection areas,

wherein the display panel comprises:

a substrate, wherein a groove recessed in a thickness direction of the substrate is defined on the substrate; and

an inorganic pattern layer on opposing sides of the groove, wherein the inorganic pattern layer comprises a pair of protruding tips protruding toward a center of the groove,

wherein the groove is between the second display element adjacent thereto and the through-area.

2 . The display apparatus of claim 1 , wherein the connection areas extend in a serpentine shape from the intermediate display area, and

adjacent connection areas are symmetrically arranged in a direction in which the pixel arrangement areas are spaced apart from one another.

3 . The display apparatus of claim 1 , wherein

the second display element comprises a pixel electrode, an intermediate layer comprising an emission layer and a counter electrode,

wherein the intermediate layer comprises:

a first functional layer between the pixel electrode and the emission layer; and

a second functional layer between the counter electrode and the emission layer,

wherein the counter electrode and at least one selected from the first functional layer and the second functional layer are separated by the pair of protruding tips and the groove.

4 . The display apparatus of claim 1 , wherein the display panel comprises:

a first side display area connected in a first direction to the front display area and bent with a first radius of curvature; and

a second side display area connected in a second direction intersecting the first direction to the front display area and bent with a second radius of curvature different from the first radius of curvature,

wherein the corner display area is between the first side display area and the second side display area.
