Description

technical field

[0001] The invention relates to the field of display technology, in particular to an array substrate and a liquid crystal display device. Background technique

[0002] VA LCD (Vertical Alignment Liquid Crystal Display) has become a common display mode of TFT-LCD for large-size TVs due to its advantages of wide viewing angle, high contrast ratio and no need for alignment friction.

[0003] In the existing VA-type LCD display technology, for a better wide-viewing-view experience, such as chromaticity and viewing angle, it is usually improved by increasing the number of pixel electrode domains. For example, by setting the main area and the sub-area with different driving voltage differences, the main area and the sub-area respectively contain 4 axis-symmetrical domains, and the difference between the front view and the side view is reduced by the characteristics of spatial and liquid crystal orientation differentiation. Small, that is to improve characteristics...
