ABSTRACT:
A display device for realizing gray-scale display by changing an amplitude of a modulation voltage which is output from a data-side driving circuit. A driving control circuit is capable of supplying a first display data signal representing (m+n) grades, obtained by adding m grades represented by a second display data signal externally input and an adjustable range n. The data-side driving circuit is capable of outputting modulation voltages having (m+n) types of amplitudes to a plurality of first electrodes in accordance with a first display data signal. The amplitude of the modulation voltage corresponding to the light emission characteristic of a prescribed light emitting layer among a plurality of light emitting layers is adjusted to an amplitude in the adjustable range n from the amplitude corresponding to the grade represented by the second display data signal.
