Abstract
A display device, including a display module, a photodetector, a processor, and an optical structure layer, is provided. The display module is used for displaying an image. The photodetector is electrically connected to the display module and is used for detecting brightness of an ambient light and outputting a sensing signal. The processor is electrically connected to the display module and the photodetector, and is used for receiving the sensing signal and outputting a command signal to the display module according to the sensing signal, so that the display module adjusts brightness of the image according to the command signal. The optical structure layer is disposed on the display module. A glossiness of the optical structure layer is between 4 GU and 35 GU, and a reflectivity of specular component included (SCI) of the optical structure layer is between 3% and 6%.
