Display device and fabrication method thereof are provided. A display includes a polymer liquid crystal cell, including a first electrode layer, a second electrode layer, and a light-scattering adjustment layer between the first electrode layer and the second electrode layer; and a light source, arranged on a first side of the polymer liquid crystal cell and configured to emit light into the light-scattering adjustment layer. The first electrode layer includes at least one first electrode. The second electrode layer includes at least one second electrode. The display region of the polymer liquid crystal cell includes a plurality of regions having a light-scattering ability increase along a direction away from the light source.
