Abstract: According to an embodiment, a display device may include a semiconductor wafer substrate, a complementary metal oxide semiconductor (CMOS) circuit layer disposed on the semiconductor wafer substrate, and a light emitting element layer disposed on the CMOS circuit layer. The light emitting element layer may include a pixel defining film partitioning a plurality of pixels, a pixel electrode disposed independently in each of the plurality of pixels, an aging wiring disposed between the plurality of pixels, a light emitting layer commonly covering the pixel electrodes of each of the plurality of pixels and the aging wiring, and a common electrode covering the light emitting layer. A portion positioned between the aging wiring and the common electrode of the light emitting layer may include an aged portion in which at least a portion of a conductive layer included in the light emitting layer is aged.

Abstract: A display device includes a first sub-pixel, and a second sub-pixel located adjacent to the first sub-pixel. Each of the first and the second sub-pixels may include: a first electrode; a pixel defining layer on the first electrode; a first emission component on the pixel defining layer and configured to emit light; a first intermediate layer on the first emission component; a second emission component on the first intermediate layer and configured to emit light; and a second electrode on the second emission component. A trench may be formed by recessing at least a portion of the pixel defining layer in a boundary area between the first sub-pixel and the second sub-pixel. The first intermediate layer may be interrupted over the trench. The second emission component may completely cover the first intermediate layer over the trench.

Abstract: A display device includes: a substrate; a first pixel electrode and a second pixel electrode on the substrate; a dummy pixel electrode between the first pixel electrode and the second pixel electrode, and to receive a dummy voltage; an emissive layer on the first pixel electrode, the second pixel electrode, and the dummy pixel electrode; and a common electrode on the emissive layer. The first pixel electrode is to receive a pixel voltage different from the dummy voltage.
