Claim:
1. A display device comprising a plurality of pixels, at least one of the plurality of pixels comprising: a light emitting element; a pixel capacitor; a first initialization transistor connected between a first voltage line and the pixel capacitor; a second initialization transistor connected between a second voltage line and the light emitting element; and a driving circuit, wherein, in a first period, the first initialization transistor is configured to connect the first voltage line to the pixel capacitor, wherein, in a second period after the first period, the driving circuit is configured to supply a compensation current from a current supply line to the pixel capacitor, wherein, in a third period after the second period, the light emitting element is configured to emit light, wherein the driving circuit includes a first transistor and a second transistor, wherein a gate of the first transistor is not connected to a gate of the second transistor, and wherein the size ratio W/L of the first transistor is at least 0.5, where W is a channel width and L is a channel length.
