  • Publication number: 20260164941
    Abstract: A display device includes: a substrate, a first planarization layer disposed on the substrate, and a second planarization layer disposed on the first planarization layer having an opening. A pixel electrode is disposed on the first planarization layer within the opening and extends along an inner side surface of the second planarization layer. A bank is disposed on the pixel electrode and has a hole smaller than the opening. The edge of the opening includes a specific curved region, and the opening is defined by the inner side surface of the second planarization layer. A specific portion of the inner side surface of the second planarization layer corresponding to the specific curved region may include at least one step to improve light extraction efficiency, enhance luminance uniformity, and provide a coating path for an organic encapsulation layer.

  • Publication number: 20250221131
    Abstract: A display device may include a substrate; transmissive areas spaced apart from each other; an area which includes sub-pixels; an over-coating layer which is disposed on the substrate and includes a base portion and a protrusion on the base portion; and an anode which is disposed in each sub-pixel and covers the base portion and a part of the protrusion. Each sub-pixel may include an emission area and an outer peripheral area which encloses the emission area. The outer peripheral area may include first outer peripheral areas opposite to adjacent other sub-pixels and second outer peripheral areas opposite to adjacent transmissive areas. Trenches may be disposed in the protrusion in the first outer peripheral areas. The anode may be disposed in the trenches in the first outer peripheral areas.
