Abstract: A display apparatus includes a substrate and a first pixel electrode disposed over the substrate, where a distance from a first portion of an upper surface of the first pixel electrode to an upper surface of the substrate is greater than a distance from a second portion of the upper surface of the first pixel electrode to the upper surface of the substrate.

Abstract: 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.

Abstract: 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.
