Abstract:
With a source voltage of a transistor driving a light emitting element set to a fixed voltage, variations in an emission luminance due to variations in the threshold voltage of the transistor are corrected. The fixed voltage is set in accordance with a signal level of a drive pulse signal on-off controlling a transistor supplying power to the first transistor.
