Abstract
The present application describes a display panel having an array substrate; a counter substrate facing the army substrate; and a light guide grating layer on a side of the array substrate distal to the counter substrate. The light guide grating layer in a three-dimensional image display mode is configured to have a plurality of light emitting regions and a plurality of light non-emitting regions alternately arranged, thereby forming a grating. The light guide grating layer is configured to emit light from the plurality of light emitting regions, and configured not to emit light form the plurality of light non-emitting regions, thereby displaying a three-dimensional image in the display panel.
