Abstract
A scanning line driving circuit selects arbitrary one of a plurality of pixels and causes the pixel to perform a current value setting operation of setting a current value of the driving current to be supplied to the light emitting element of the pixel in a frame period before the pixel is selected again and a light emission operation of emitting light by supplying the driving current to the light emitting element. The scanning line driving circuit controls, in common with the plurality of pixels, a duty ratio corresponding to the frame period of the light emission period in which the light emission operation is performed. The scanning line driving circuit disperses time differences between a current value setting timing and a start timing of the light emission period in the plurality of pixels when the duty ratio is equal to or smaller than a predetermined value.
