Abstract

A display device includes a display panel and a grating layer inside or outside the display panel. The display panel includes R pixels, G pixels and B pixels. The grating layer includes a R grating region, a G grating region and a B grating region; along a direction from a center of a central area of the view field of the display device to a non-central area of the view field, each of grating periods of the R, G and B grating regions gradually decreases; and lights emitted from positions of the display device corresponding to the R pixel, the G pixel and the B pixel are emitted respectively along straight lines formed by the position of the R pixel and the viewer, formed by the position of the G pixel and the viewer and formed by the position of the B pixel and the viewer.
