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.
