Abstract

The invention provides a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a first substrate, a second substrate opposite to the first substrate and a first liquid crystal layer located between the first substrate and the second substrate. The liquid crystal display panel further comprises a dimming layer located on the side, close to the first substrate, of the second substrate, and the dimming layer comprises a plurality of shading pieces arranged at intervals; and a first light switching layer which is positioned on one side, far away from the first substrate, of the second substrate, and the first light switching layer can control the visual angle of emitted light. By arranging the dimming layer, the purpose of shrinking the visual angle can be achieved; and meanwhile, the first light switching layer is additionally arranged, and electric fields are applied to the two sides of the first light switching layer, so that free switching of wide and narrow viewing angles of the liquid crystal display panel can be realized, and a peep-proof function can be realized.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] A liquid crystal display (LCD for short) is one of the most widely used flat panel display devices at present, and it is widely used in smart phones, computers, televisions and the like. With the continuous development of Internet technology and the emergence of various application software, people can even complete most of the things in life and work through a smart phone, tablet computer, etc., such as online shopping, chatting, watching videos, and online payment. , electronic payment, stock trading and so on. [0003] With the continuous development of display technology, the viewing angle of the display panel is getting wider and wider. The viewing angle of the current display panel is close to 180 degrees. Users can watch the content displayed on the display panel f...
