Abstract

The invention relates to a visual angle control element and a manufacturing method thereof, and a liquid crystal display device. The visual angle control element comprises a first transparent substrate, a first transparent electrode layer, a patterned transparent photoresistor layer, a second transparent electrode layer and a second transparent substrate which are sequentially laminated from bottom to top, wherein the patterned transparent photoresistor layer comprises a plurality of rectangular transparent photoresistors which are arranged in a matrix mode; the rectangular transparent photoresistors are separated by strip gaps which are distributed longitudinally and transversely; and the strip gaps are filled with polymer dispersed liquid crystals. When in the narrow visual angle mode, the first transparent electrode layer and the second transparent electrode layer are not powered up, and the polymer dispersed liquid crystals are in the scattering state; and when in the wide visual angle mode, the first transparent electrode layer and the second transparent electrode layer are powered up, and the polymer dispersed liquid crystals are in the transparent state. The visual angle control element is simple in technique, has favorable effects, and can switch the visual angle freely. The visual angle control element does not need additional backlight or pixel design.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a viewing angle control element, a manufacturing method, and a liquid crystal display device. Background technique [0002] With the development of science and technology and the improvement of people's quality of life, liquid crystal display devices have been seen everywhere in life, and people's requirements for liquid crystal display devices are getting higher and higher, and they are beginning to pursue large display screens, fast response speeds and higher resolution. [0003] At present, liquid crystal displays are gradually developing towards wide viewing angles. For example, portable electronic display devices with wide viewing angles such as mobile terminals, flat panel displays, and notebook computers. The design of wide viewing angles allows users to see complete and undistorted picture. However, when it comes to the user's personal privacy and important inform...
