A display apparatus includes a display panel having a display unit. A touch sensor layer is disposed on the display panel. A window layer is disposed on the touch sensor layer. The window layer has a first refractive index and includes a first surface and a second surface opposite the first surface. An insulation layer is disposed between the window layer and the touch sensor layer. The insulation layer has a second refractive index that is greater than the first refractive index.

Display apparatus having arbitrary shape

An organic light-emitting display apparatus in which a plurality of pixels are arranged in a first direction and a second direction crossing the first direction includes: an organic light-emitting device disposed on a substrate, wherein the organic light-emitting device is included in each of the plurality of pixels; a pixel-defining film covering edges of a pixel electrode of the organic light-emitting device and having an opening exposing a portion of the pixel electrode to define an emission region; and a conductive layer between the substrate and the organic light-emitting device. The conductive layer includes first extension portions extending in the first direction and second extension portions extending in the second direction. The emission region of each of the plurality of pixels overlaps one of cross portions where the first extension portions and the second extension portions cross each other.

Organic light-emitting display apparatus

A display apparatus includes a substrate including a display area and a peripheral area disposed outside of the display area, a plurality of wiring lines disposed in the peripheral area, and an interlayer insulating layer covering the plurality of wiring lines. The interlayer insulating layer includes an upper surface having a first concave-convex surface corresponding to the plurality of wiring lines. The display apparatus further includes a first conductive layer disposed on the interlayer insulating layer and including a second upper surface having a second concave-convex surface corresponding to the first concave-convex surface, a planarization layer disposed on the first conductive layer and having a flat upper surface, a second conductive layer disposed on the planarization layer and having a flat upper surface, and a polarization plate disposed on the second conductive layer.

Display apparatus

A display device includes a base substrate including a front surface having an active area and a peripheral area; a plurality of pixels; a plurality of first signal lines on the active area, each extending in a first direction, spaced apart from each other in a second direction crossing the first direction; a plurality of second signal lines, crossing the first signal line in an insulation manner; a plurality of first conductive patterns, spaced apart from each other in the first direction; a second conductive pattern overlapping the first conductive patterns and having a top surface waved in the first direction; and an optical member on the second conductive pattern, wherein the top surface of the second conductive pattern includes flat portions and protruding portions, that are alternately arranged in the first direction, and the protruding portions protrude from the flat portions toward the optical member.

Display device

An organic light emitting display device includes a step difference compensation pattern that may reduce imbalance or asymmetry below a pixel electrode. The step difference compensation pattern is on a first protection layer and is separated from a conductive line. A second protection layer is on the conductive line and the first step difference compensation pattern. An organic light emitting layer is between the first electrode and a second electrode. The first electrode is on the second protection layer and overlaps at least a part of the conductive line and at least a part of the first step difference compensation pattern.
