Abstract
A display apparatus with improved light emission uniformity includes a pixel. The pixel includes a driving thin-film transistor (TFT); a storage capacitor; a driving semiconductor layer; a first electrode layer; a second electrode layer; a pixel electrode; a pixel-defining layer defining a light-emitting region; and a conductive layer interposed between the first electrode layer and the pixel electrode and including an extending portion that at least partially overlaps the light-emitting region in a plane view to pass over a central portion of the light-emitting region.
Claims1
A display apparatus comprising a pixel including a driving thin film transistor (TFT) and a storage capacitor,
- wherein the pixel comprises:
- a driving semiconductor layer including a driving channel region, a driving source region, and a driving drain region;
- a first electrode layer at least partially overlapping the driving channel region in a plane view;
- a second electrode layer on the first electrode layer and overlapping the first electrode layer in the plane view;
- a pixel electrode on the second electrode layer;
- a pixel-defining layer on the pixel electrode and having an opening exposing at least a portion of an upper surface of the pixel electrode and defining a light-emitting region;
- and
- a conductive layer between the first electrode layer and the pixel electrode and including an extending portion at least partially overlapping the light-emitting region to pass over a central portion of the light-emitting region.
