Patent ID: 7800562

Claim:
A display device in which image data is subjected to digital-analog conversion processing to produce a drive signal and a display part formed by arranging pixels each employing a current-driven light-emitting element in a matrix is driven based on the drive signal, the display device comprising: a basic reference voltage generation circuit configured to generate a plurality of basic reference voltages by varying a voltage in accordance with control data; and a plurality of voltage divider circuits configured to each produce a plurality of reference voltages by dividing the plurality of basic reference voltages by resistors, for a respective one of color data included in the image data; wherein at least the basic reference voltage corresponding to a black level is supplied to the plurality of voltage divider circuits in common, and the basic reference voltages closer to the black level than a voltage corresponding to a center value of the drive signal are each supplied to a respective one of the plurality of voltage divider circuits for a respective one of the color data.
