Abstract
A display device includes a plurality of light-emitting elements arrayed in a display region, a first pixel circuit and a second pixel circuit coupled to each of the light-emitting elements, a first drive transistor provided to the first pixel circuit and configured to supply a first drive current to the light-emitting element, a second drive transistor provided to the second pixel circuit and configured to supply a second drive current to the light-emitting element, a drive circuit configured to supply a video signal to the first drive transistor and the second drive transistor, a first coupling switching transistor provided between the first drive transistor and the light-emitting element, and a second coupling switching transistor provided between the second drive transistor and the light-emitting element. The first coupling switching transistor and the second coupling switching transistor are turned off in a non-emission period of the light-emitting element.
