1. A display device, comprising:
a pixel array unit that includes a plurality of pixels in a two-dimensional arrangement in a matrix,
wherein each pixel of the plurality of pixels includes:
a light emitting element; and
a driving transistor configured to drive the light emitting element; and
a signal output unit configured to:
output, to each pixel of the plurality of pixels, a first signal voltage of a video signal and a first initialization voltage,
wherein the first initialization voltage is for initialization of a gate voltage of the driving transistor;
vary the first initialization voltage based on the first signal voltage of the video signal;
set a voltage between a gate electrode of the driving transistor and a source electrode of the driving transistor to a first value for a first luminance region of the display device; and
set the voltage between the gate electrode of the driving transistor and the source electrode of the driving transistor to a second value for a second luminance region of the display device, wherein
the second value is higher than the first value, and
a luminance of the second luminance region is lower than a luminance of the first luminance region.
