Abstract
An organic light emitting display device includes a first electrode in an emission area of a subpixel; a pixel defining layer surrounding the first electrode in a non-emissive area of the subpixel; a light emitting layer on the first electrode; a second electrode on the light emitting layer; a first encapsulation layer on the second electrode; and a color filter on the first encapsulation layer in the subpixel.
Claims22
An organic light emitting display device, comprising:
- a first electrode in an emission area of a subpixel;
- a pixel defining layer surrounding the first electrode in a non-emissive area of the subpixel;
- a light emitting layer on the first electrode;
- a second electrode on the light emitting layer;
- a first encapsulation layer on the second electrode;
- and
- a color filter on the first encapsulation layer in the subpixel,
- wherein the pixel defining layer includes:
- a first pixel defining layer;
- a second pixel defining layer on the first pixel defining layer, a width of the second pixel defining layer at any height thereof is wider than a width of the first pixel defining layer at any height thereof;
- a first metal layer on the second pixel defining layer;
- and
- a third pixel defining layer on the first metal layer;
- wherein a thickness of the third pixel defining layer is thicker than a thickness of each of the first pixel defining layer, the second pixel defining layer, and the first metal layer.
