Abstract
Each pixel circuit includes a driving transistor, a first switching transistor and a second switching transistor. The driving transistor includes first and second gate electrodes. The first switching transistor is connected to a first data line and the first gate electrode, and controlled to be ON or OFF in accordance with a scanning signal supplied to a scanning line. The second switching transistor is connected to a second data line and the second gate electrode, and controlled to be ON or OFF in accordance with the scanning signal supplied to the scanning line. The voltage of the second data signal varies in the opposite direction to variation of voltage of the first data signal for at least a part of a gray scale range of the light-emitting element including the lowest gray scale level from the lowest gray scale level to the highest gray scale level.
