    摘要: A display panel includes a light guide plate, a substrate, a reflector and a liquid crystal layer. A refractive index of the liquid crystal layer can vary between a minimum liquid crystal refractive index and a maximum liquid crystal refractive index. One side, facing the substrate, of the light guide plate includes a light entry region, light at least partially enters the liquid crystal layer through the light entry region and is propagated towards the reflector. The maximum liquid crystal refractive index is greater than a refractive index of the reflector, and the minimum reflective index is not greater than the refractive index of the reflector. When the refractive index of the liquid crystal layer is greater than the reflective index of the reflector, the reflector reflects at least a part of light entering the liquid crystal layer from the light entry region to the light guide plate.
