Abstract: According to one embodiment, a display device includes a plurality of pixel units which each includes a light-emitting element and a pixel circuit, a plurality of first scan lines and second scan lines, a plurality of video signal lines, a controller which controls a scan line drive circuit and a signal line drive circuit, wherein the pixel circuit comprises an output switch, a drive transistor, a capacitance, and a pixel switch, wherein the controller controls a reset operation, a cancellation operation, a correction operation, and a light-emitting operation, and the controller deforms a waveform of a control signal which is supplied from the second scan line in a manner that a time of transitioning the pixel switch from an on-state to an off-state is longer than the time of transitioning by a non-deformed control signal, when writing the video voltage signal in the correction operation.
