Abstract: An organic light-emitting display device including: a substrate; a pixel electrode on the substrate; a pixel defining film on the pixel electrode and having a first opening at least partially exposing the pixel electrode; an organic light-emitting layer on the exposed portion of the pixel electrode; a common electrode on the organic light-emitting layer and the pixel defining film; an encapsulation layer on the common electrode; a black matrix on the encapsulation layer and having a second opening overlapping the first opening; and a plurality of first sensing lines on the black matrix and surrounding the pixel electrode in a plan view to define a pixel region. At least portions of the first sensing lines defining the pixel region do not overlap the common electrode in the pixel region.

Abstract: A display device including a substrate, a source electrode and a drain electrode on the substrate, the source electrode and the drain electrode being spaced apart from each other, a first planarization layer on the source electrode and the drain electrode, a second planarization layer on the first planarization layer, and a first electrode on the second planarization layer. A step difference between a top of the first planarization layer and a top of the drain electrode is 100 Å or less.

Abstract: A display device including a substrate, a source electrode and a drain electrode on the substrate, the source electrode and the drain electrode being spaced apart from each other, a first layer on the source electrode or the drain electrode, a second layer directly on the first layer, and a first electrode on the second layer. A step difference between a top of the first layer and a top of the drain electrode is 100 Å or less.

Abstract: A display device includes a display panel and a touch sensor on the display panel. The display panel includes: a base layer; a light emitting element having a first electrode on the base layer; a pixel defining layer including an opening region that exposes a portion of the first electrode of the light emitting element; and an encapsulation layer covering the light emitting element and the pixel defining layer. The touch sensor has: a first conductive pattern on the encapsulation layer; a color filter on the encapsulation layer to cover the first conductive pattern, the color filter including a first region including a lens part and overlaps the opening region of the pixel defining layer and a second region overlaps the pixel defining layer; a second conductive pattern on the second region of the color filter; and a black matrix on the second conductive pattern.
