Abstract

The invention provides a liquid crystal display device with a switchable visual angle. The liquid crystal display device comprises a first base plate, a second base plate and a liquid crystal layer arranged between the first and second base plates; a first electrode is placed on the first base plate; the second base plate is opposite to the first base plate; the second base plate is provided with a second electrode and a third electrode; liquid crystal molecules in the liquid crystal layer is negative liquid crystal; and a first primary inclined angle of the liquid crystal molecules of the liquid crystal and adjacent to the first base plate has the opposite direction and equal size as a second primary inclined angle of the liquid crystal molecules of the liquid crystal and adjacent to the second base plate. Without an increase of thickness and cost of the liquid crystal display device, switch between the wide visual angle and the narrow visual angle can be achieved; and convenient operation and great flexibility can be realized.

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] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as light and thin, energy saving, no radiation, etc., therefore 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 undis...
