Abstract
A display device includes a plurality of pixels, wherein each pixel includes: a light emitting element; a first capacitor connected between a first node and a second node; a driving transistor having an input terminal, an output terminal, and a control terminal connected to the second node where the driving transistor supplies a driving current to the light emitting element to emit light; a first switching unit supplying a first reference voltage to the driving transistor according to a first scanning signal and connecting the first node to a data voltage or the driving transistor; and a second switching unit supplying a driving voltage to the driving transistor according to a second scanning signal and connecting the first node to the data voltage. Accordingly, variations in threshold voltage of the driving transistor can be compensated for so that it is possible to display a uniform image.
