Abstract
The invention provides a liquid crystal display device capable of achieving visual angle switching. The liquid crystal display device comprises a first substrate, a second substrate arranged opposite to the first substrate, and a liquid crystal layer located between the first substrate and the second substrate, wherein liquid crystal molecules in the liquid crystal layer are negative liquid crystal molecules, a pixel electrode and a common electrode are arranged on the second substrate, a first electrode is arranged on the surface, facing towards the liquid crystal layer, of the first substrate, the range of the initial pretilt angles of the liquid crystal molecules, adjacent to the first substrate, of the liquid crystal layer is larger than or equal to 30 degrees or smaller than 90 degrees, and the liquid crystal molecules, adjacent to the second substrate, of the liquid crystal layer are in homogeneous alignment. According to the liquid crystal display device capable of achieving visual angle switching, the purpose of switching between a wide visual angle and a narrow visual angle can be achieved without increasing the thickness of a liquid crystal display and the cost of a backlight device.
Description
technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device capable of switching between a wide viewing angle and a narrow viewing angle. Background technique [0002] Liquid crystal display devices are widely used in electronic devices such as televisions, personal computers, tablet computers, personal digital assistants (PDAs), mobile phones, and digital cameras due to their advantages of thinness, lightness, energy saving, and no radiation. At present, wide viewing angles are the mainstream development direction of liquid crystal display devices, and people can see a complete and undistorted picture when viewing the screen of the wide viewing angle liquid crystal display device from different directions. However, when personal privacy and important information are involved, the use of a display device with a wide viewing angle may cause inconvenience to people in some occasions. [0003] For example, o...
