Claim:
1. A display device comprising a first pixel at a region defined by a first scan line and a first data line, wherein the first pixel comprises a switching transistor comprising a control terminal connected to the first scan line and an input terminal connected to the first data line, and is configured to be turned on by an on voltage of a scan signal from the first scan line; a first transistor comprising a first control terminal connected to the first scan line, a first input terminal connected to the first data line, and a first output terminal connected to the first control terminal; and a second transistor comprising a second control terminal connected to the first output terminal, a second input terminal configured to receive a base voltage, and a second output terminal connected to the second control terminal, wherein the first transistor is configured to convert light into a first current to be outputted to the first output terminal, in response to an off voltage of the scan signal, and wherein the second transistor is configured to convert light into a second current to be outputted to the second output terminal, in response to an off voltage of the scan signal.
