Abstract:
1. A display device provided with a display portion having (i) a pixel, which has a light-emitting element for self-light emitting according to a current amount and a pixel circuit, which controls a current applied to the light-emitting element according to a voltage signal, (ii) a scanning line supplying a selection signal, by which a pixel to be emitted is selected, to the pixel at a predetermined scanning cycle, and (iii) a data line supplying the voltage signal, which corresponds to an input video signal, to the pixel, the display device comprising: an average luminance calculation portion that calculates an average luminance of the input video signal during a predetermined period; and a light-emitting time setting portion that sets a real duty defining light-emitting time for light emitting of the light-emitting element every one frame according to the average luminance calculated in the average luminance calculation portion, wherein,
