Abstract

A display device includes at least one spatial light modulator displaying an image, a surface light source device providing an image display light from a rear direction of the spatial light modulator to the spatial light modulator, and at least one image transmission member forming a display path of an image displayed through at least one spatial light modulator, the surface light source device comprises an organic light emitting display surface in which light emitting pixels performing a surface light emission are disposed, and an emission driving circuit setting a light emission compensation value for the each of the block areas according to an average value of light emission grayscale deviation for each of the block areas of the organic light emitting display surface and compensating light emission grayscale in respect to the light emitting pixels by using the light emission compensation value for each of the block areas.
