Abstract
An organic light emitting display device includes a reflective electrode in a pixel region on a substrate and including a concave portion defining a concave furrow, a first filling pattern filling the concave furrow, a first electrode on the first filling pattern and on a portion of the reflective electrode around the first filling pattern, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer.
Claims17
An organic light emitting display device comprising:
- a reflective electrode in a pixel region on a substrate, and including a concave portion defining a concave furrow;
- a first filling pattern filling the concave furrow;
- a first electrode on the first filling pattern and on a portion of the reflective electrode around the first filling pattern;
- an organic light emitting layer on the first electrode;
- a second electrode on the organic light emitting layer;
- a bank disposed on a boundary of the pixel region;
- a passivation layer provided below the reflective electrode, the passivation layer including a concave surface on which the concave portion of the reflective electrode is formed;
- and
- a second filling pattern filling a drain contact hole of the passivation layer,
- wherein the bank overlaps with an edge portion of the concave furrow of the reflective electrode,
- wherein a drain electrode of a thin film transistor in the pixel region and the reflective electrode are electrically connected with each other through the drain contact hole, and
- wherein the second filling pattern is surrounded by the drain electrode, a portion of the reflective electrode and a portion of the first electrode which contacts the portion of the reflective electrode.
