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 thereon. The second substrate is provided with a second electrode, a third electrode and a second alignment film thereon. The liquid crystal layer is disposed between the first alignment film and the second alignment film, and includes a plurality of liquid crystal molecules. All of the liquid crystal molecules in the liquid crystal layer are tilted at the same pretilt angle relative to the alignment films. When no bias voltage is applied to the first electrode, the LCD shows a narrow viewing angle; and when a bias voltage is applied to the first electrode, the LCD shows 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, notebook computers, personal digital assistants, tablet computers, mobile phones and other portable electronic devices with wide viewing angles all adopt wide viewing angle technology, so that people can see complete and undistorted ima...
