Abstract: A display device is disclosed. The display device includes a display panel, and a grating layer arranged inside or outside of the display panel. Along a direction pointing from a center of a sight concentration area of the display device to a non-sight concentration area of the display device, a grating period of the grating layer decreases gradually. When incident light incident on the grating layer is diffracted at an area of the grating layer corresponding to the non-sight concentration area of the display device, the obtained light of non-zero order diffraction falls into a sight of a viewer.
