Abstract
The present application provides a display device, when the display device is in a first display mode, a transmittance of first optical units to light is less than a transmittance of second optical units to light, so that diffracted light is emitted due to a phenomenon that apertures in a diffraction panel are alternating between light and dark. After the diffracted light emitted by the diffraction panel passes through a display panel, the display device has a wide viewing angle in the first display mode.
