Abstract
A display device includes a substrate, a first electrode disposed on the substrate, a first pixel-defining layer disposed on the first electrode, the first pixel-defining layer having a first opening exposing at least a portion of the first electrode and including a pigment, and a second pixel-defining layer disposed on the first pixel-defining layer and including a dye.
Claims15
A display device comprising:
- a substrate;
- a first electrode disposed on the substrate;
- a first pixel-defining layer disposed on the first electrode, the first pixel-defining layer having a first opening exposing at least a portion of the first electrode and comprising a negative photosensitive material and a black pigment;
- and
- a second pixel-defining layer disposed on the first pixel-defining layer and comprising a positive photosensitive material and a black dye, wherein the first pixel-defining layer has an optical density of 1 or more, and
- an optical density of the second pixel-defining layer is less than an optical density of the first pixel-defining layer.
3 more elements
A display device comprising:
- a plurality of pixels, each pixel comprising a pixel electrode;
- and
- a pixel-defining layer disposed between the plurality of pixels to define the plurality of pixels,
- wherein the pixel-defining layer comprises:
- a first pixel-defining layer disposed to at least partially cover the pixel electrode and comprising a negative photosensitive material and a black pigment;
- and
- a second pixel-defining layer disposed on the first pixel-defining layer to at least partially cover the pixel electrode and comprising a positive photosensitive material and a black dye,
- the first pixel-defining layer has an optical density of 1 or more, and
- an optical density of the second pixel-defining layer is less than an optical density of the first pixel-defining layer.
