Among them, each pixel unit contains a thin film transistor installed on the bottom substrate and a pixel electrode installed on the bottom substrate, and electrical connecting the thin film transistor, and the pixel electrode has a number of main slits.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display panel, in particular to a multi-region vertical alignment liquid crystal display panel. 【Background technique】 [0002] Liquid crystal displays have been widely used in various electronic products, such as mobile phones, personal digital assistants (PDAs) and notebook computers (notebooks). It plays a very important role, and gradually replaces the cathode ray tube (CRT) display to become the mainstream of the market. However, the viewing angle of the traditional liquid crystal display is not wide enough, which is a limiting condition for its development. Therefore, a multi-domain vertical alignment (MVA) liquid crystal display panel that can increase the viewing angle has been developed accordingly. [0003] Please refer to FIG. 1A . FIG. 1A is a schematic structural diagram of a conventional multi-domain vertical alignment liquid crystal display panel 10 . As shown in FIG. 1A, the multi-re...
