Problems solved by technology
[0004] However, compared with the widespread use of phase compensation films for TN-type liquid crystal displays, phase compensation films for OCB-type liquid crystal displays can only be provided by very few manufacturers, and the production quantity of phase compensation films is quite small, thus greatly limiting Production and Manufacture of OCB Type Liquid Crystal Display

Embodiment Construction
[0023] Please refer to FIG. 1 , which shows a schematic diagram of a backlight module and a liquid crystal display panel according to a first embodiment of the present invention. The liquid crystal display device of this embodiment includes a liquid crystal display panel 100 and a backlight module 101 . The liquid crystal display panel 100 is disposed above a backlight module 101 to form a liquid crystal display device. The backlight module 101 can be an edge lighting backlight module or a bottom lighting backlight module, wherein the backlight module 101 is preferably provided with an optical film set (not shown) to enhance the backlight effect. The optical film set can be, for example, a diffuser sheet, a prism sheet, a reverse prism sheet (Turning Prism Sheet), a Brightness Enhancement Film (BEF), a reflective Brightness Enhancement Film (Dual Brightness Enhancement Film, DBEF), a non-multi Diffused Reflective Polarizer Film (DRPF) or any combination of the above. The lig...

Abstract
The invention provides a liquid crystal display (LCD) panel and an LCD device. The LCD device includes the LCD panel and a backlight module. The LCD panel includes a first base plate, a second base plate, a liquid crystal layer, two phase compensation films and two double-shaft material films. The liquid crystal layer is arranged between the first base plate and the second base plate, wherein the liquid crystal layer is provided with liquid crystal molecules arranged in a bent form. The two phase compensation films are arranged on the same side or the two opposite sides of the liquid crystal layer respectively. The two double-shaft material films are arranged on at least one of the two phase compensation films. The invention can guarantee the manufacture and production of the LCD device.
Description
technical field [0001] The present invention relates to a liquid crystal display panel and a liquid crystal display device, and in particular to an optically compensated bend mode (Optically Compensated Bend Mode, OCB) liquid crystal display panel and a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of high image quality, small size, light weight, low driving voltage, and low power consumption, so it is widely used in personal digital assistants (PDAs), mobile phones, video recording and playback Computers, notebook computers, desktop monitors, car monitors, and projection TVs and other electronic products. [0003] At present, most liquid crystal displays are twisted nematic (TN) liquid crystal displays, which have disadvantages such as narrow viewing angle, slow response speed, and large color dispersion. Compared with twisted type LCDs, optically compensated bend mode (OCB) LCDs may have advantages such as wid...
