Abstract
A display device and a dimming device are provided. A dimming layer is located between a first polarizer and a second polarizer whose transmission axes are parallel to each other. When the display device is in a first display mode, long axes of the liquid crystal molecules distributed in the first polymer network are arranged along the second direction, and long axis of the liquid crystal molecules distributed in the second polymer network are arranged along the third direction. The third direction and the second direction respectively point to opposite sides of a normal line of the first polarizer.
