摘要
Provided is a perspective-switchable display device. The perspective-switchable display device comprises a light alignment module and a light perspective switching module, wherein the light perspective switching module is provided in a light exit side of the light alignment module, and the light perspective switching module comprises a first conducting film, a second conducting film, a switching structure film and an electro-optic material. The first conducting film is provided at a side close to the light alignment module, the second conducting film and the first conducting film are provided oppositely, and there is a gap between the first conducting film and the second conducting film. The switching structure film is provided in the gap, and a surface of the switching structure film away from the first conducting film or away from the second conducting film is a first surface, and the first surface is a concave-convex surface. The first surface comprises a plurality of micro-structures arranged in sequence. The electro-optic material is provided in the gap and is provided on the first surface. The perspective-switchable display device has a simple optical structure, consumes less energy, and can realize privacy display without increasing the number of light sources.
