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.
