Abstract:
A display apparatus includes a display panel including a plurality of pixels configured to display an image, each of at least one of the plurality of pixels including a pixel circuit and a light emitting device connected to the pixel circuit, wherein the pixel circuit includes a driving transistor controlling a driving current flowing at the light emitting device, a data supply transistor selectively providing a data voltage to a first node which is a source electrode of the driving transistor, a first light emitting control transistor selectively connecting the first node to a second node which is an electrode of the light emitting device, a first capacitor connected between the second node and a fourth node which is a gate electrode of the driving transistor, and a second capacitor connected between the second node and a gate electrode of the data supply transistor.
