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.

Abstract: Embodiments of the present application disclose a display panel and a preparation method thereof, and a display device. The display panel comprises a polymer liquid crystal cell and a light source. The polymer liquid crystal cell comprises a first region close to the light source and a second region away from the light source, and the second region has a higher haze than the first region, thereby reducing the light emitting intensity close to the light source region and increasing the light emitting intensity away from the light source region, so that light guide and light emitting in each region of the polymer liquid crystal cell uniform.
