Abstract

A displayed light-adjustment device includes two light-transmitting layers which are arranged oppositely, a display module, and an adjustable light-shading layer. The display module is stacked between the light-transmitting layers. The adjustable light-shading layer is interposed between the first light-transmitting layer and the display module, and the light transmittance of the adjustable light-shading layer is adjustable. When the adjustable light-shading layer is powered off, the light transmittance of the adjustable light-shading layer is greater than 75%, and when the adjustable light-shading layer is powered on, an ultraviolet resistance value of the adjustable light-shading layer is greater than 99%.
