Problems solved by technology

[0003] The defect of this scheme is that the "hole" opening 24a directly cuts off the electrode, so the opening 24a does not function as an electrode. When a voltage is applied to the upper and lower plates, the electric field at the center of the opening 24a is almost zero, so the liquid crystal molecules Basically perpendicular to the array substrate, it will appear as figure 2 The black point shown, reduces the brightness and affects the display quality

Abstract

The invention discloses an array substrate, a liquid crystal display device and a manufacturing method for the array substrate. The array substrate comprises an insulating layer and an electrode layer densely provided with a plurality of pixel electrodes; the array substrate has a plurality of field change areas; the thickness of the insulating layer in the field change areas is not consistent with that of the insulating layer in other areas; and the pixel electrodes can be electrified in the field change areas and other areas. Because the field change areas are adopted, during electrification, the electric field strength on the surfaces of the field change areas is not consistent with that on the surfaces of the electrodes, power lines near the areas are inclined, liquid crystal molecules can deflect around the field change areas to specific different directions, and a display visual angle is widened; the electrode effect still exists in the field change areas, so a strong electric field effect still exists in the areas, the number of liquid crystal molecules in a vertical state can be reduced, and the size of a dark spot is reduced; therefore, the brightness is improved and a large-visual-angle display effect is improved.

Description

technical field [0001] The present invention relates to the field of liquid crystal display, and more specifically, relates to an array substrate, a liquid crystal display device and a manufacturing method of the array substrate. Background technique [0002] In VA-type liquid crystal (Vertical Alignment Mode), which is widely used now, when the power is turned off, the liquid crystal molecules are aligned perpendicular to the array substrate and are axially symmetrical, and the backlight cannot pass through. Deflection, but the deflection direction remains the same, resulting in the phenomenon that the contrast of the display screen is reduced or even the gray scale is reversed when viewed from different angles. In order to improve the display effect of VA-type liquid crystals at large viewing angles, US Patent No. 6,822,715 (B2) proposes an improvement scheme from the perspective of pixel electrode design: figure 1 As shown, a number of "hole" openings 24a are made on the...
