Problems solved by technology

However, in this eight-domain pixel architecture, a thin film transistor device is generally added to adjust the voltage division ratio, which will cause the pixel aperture ratio / native transmittance to be limited; on the other hand, in order to prevent the risk of crosstalk, it is generally necessary to increase DBS electrodes and other electric field shielding will further limit the increase in aperture ratio

Abstract

The invention discloses an array substrate and a liquid crystal display device, the array substrate comprises a plurality of scanning lines arranged in the horizontal direction, a plurality of data lines arranged in the vertical direction and a plurality of pixel units arranged in an array; and any pixel unit comprises a pixel electrode comprising a main area pixel electrode and a secondary area pixel electrode; and a thin film transistor comprising a first thin film transistor for controlling the main area pixel electrode and a second thin film transistor for controlling the secondary area pixel electrode, wherein the main area pixel electrode and the secondary area pixel electrode are arranged on the same side of the first thin film transistor and the second thin film transistor. Throughthe design, the aperture opening ratio of the pixel area can be effectively improved.

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...
