摘要： A display apparatus including pixels, each including a driving transistor comprising a first terminal, a second terminal, a first gate, and a second gate electrically connected to the second terminal. Each pixel further includes a first transistor electrically connected to a driving voltage line and the first terminal of the driving transistor, a second transistor electrically connected to the second terminal of the driving transistor and a light-emitting diode, a first capacitor electrically connected to the first gate of the driving transistor and the second terminal of the driving transistor, and a second capacitor electrically connected to the driving voltage line and the second terminal of the driving transistor. A timing at which a first gate signal is applied to a gate of the first transistor and a timing at which a second gate signal is applied to a gate of the second transistor are different from each other.

摘要： 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.
