Problems solved by technology

[0005] However, in order to realize the pre-tilt of the liquid crystal molecules in the above-mentioned liquid crystal display panel, it is necessary to add protrusions or cracks on the ITO substrate, and the protrusions and cracks need to be formed on the array substrate of the liquid crystal display panel through precise processes such as photolithography. Realization; this not only increases the manufacturing process steps, but also affects the product yield and increases the manufacturing cost

Abstract

The invention provides a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a first substrate and a second substrate opposite to the first substrate; liquid crystal molecules are sandwiched between the first substrate and the second substrate; a transparent electrode layer is arranged on one side of the first substrate close to the liquid crystal molecules; a plurality of sub-pixel electrodes are arranged on one side of the second substrate close to the liquid crystal molecules; each sub-pixel electrode comprises a polygonal display area; at least two sides of display areas of adjacent sub-pixel electrodes are adjacent; each sub-pixel electrode and the transparent electrode layer form a liquid crystal capacitor; and the voltage polarity of each sub-pixel electrode relative to the transparent electrode layer of the first substrate is opposite to that of an adjacent sub-pixel electrode relative to the transparent electrode layer of the first substrate. By comparing the manufacturing process of the liquid crystal display panel with the prior art, manufacturing process steps are reduced, the product yield is high and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is a very common display now, and it has the advantages of small size, light weight, power saving, low radiation, and easy portability. Among various display modes of liquid crystal displays, a vertical alignment (VA) display mode liquid crystal display is widely welcomed in the market due to its advantages such as high contrast ratio and wide viewing angle. [0003] In the LCD of VA display mode, vertically aligned (VA) liquid crystal molecules are vertically arranged in the liquid crystal layer in the liquid crystal cell relying on the surface riveting energy of the alignment film layer, when an electric field is applied to the ITO substrate on both sides of the liquid crystal cell The liquid crystal molecules i...
