Abstract

An LCD with switchable viewing angle includes a first substrate, second substrate, and a liquid crystal layer. The first substrate is provided with a first electrode and a first alignment film. The second substrate is provided with a second electrode, a third electrode and a second alignment film. The liquid crystal molecules adjacent to the first alignment film are tilted at a first pretilt angle. The liquid crystal molecules adjacent to the second alignment film are tilted at a second pretilt angle. The first pretilt angle and the second pretilt angle have the same magnitude but are contrary in direction. When no bias voltage is applied to the first electrode, the LCD is displayed with a narrow viewing angle; and when a bias voltage is applied to the first electrode, the LCD is displayed with a wide viewing angle.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device with a switchable viewing angle. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thinness, energy saving, and no radiation, so it has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] At present, wide viewing angles belong to the mainstream development direction of liquid crystal displays. For example, portable electronic devices with wide viewing angles such as notebook computers, personal digital assistants, tablet computers, and mobile phones all use wide viewing angle technology, so that people can see the full and undistorted dis...
