1. A display panel, comprising:
a polymer liquid crystal cell comprising a polymer dispersed liquid crystal; and
a light source disposed outside of at least one side end of the polymer liquid crystal cell;
wherein 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; and
wherein droplet size of the polymer dispersed liquid crystal in the second region is smaller than droplet size of the polymer dispersed liquid crystal in the first region, and droplet number of the polymer dispersed liquid crystal in the second region is larger than droplet number of the polymer dispersed liquid crystal in the first region.
