Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0034] image 3 It is a structural schematic diagram of the pixel unit of the edge switch mode liquid crystal display device according to the first embodiment of the present invention. Such as image 3 As shown, the pixel unit 30 includes four sub-pixel units 31a-31d arranged in a 2×2 array, and each sub-pixel unit 31a-31d includes a pixel electrode 311a-311d.

[0035] Wherein, the pixel electrode 311 of each sub-pixel unit 31 has a different domain tilt direction from the pixel electrodes of the sub-pixel units adjacent in the horizontal direction and the pixel electrodes of the sub-pixel units adjacent in the vertical direction.

[0036] In the present invention, the domain tilt direction refers to the direction perpendicular to the direction of the electric field generated by the pixel electrod...

Abstract

The invention discloses a pixel unit and an array substrate for a fringe switching mode liquid crystal display device. The pixel unit comprises four sub-pixel units arranged in a 2*2 array form; each sub-pixel unit comprises a pixel electrode; the pixel electrode of each sub-pixel unit, the pixel electrode of the sub-pixel unit adjacent to the former sub-pixel unit in the horizontal direction, and the pixel electrode of the sub-pixel unit adjacent to the former sub-pixel unit in the vertical direction have different domain tilting direction. The invention further provides the array substrate of the pixel unit. By the use of the pixel unit and the array substrate, the problem that cross stripes of non-uniform brightness are caused when the existing fringe switching mode liquid crystal display device is observed at a large angle of view is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacturing, in particular to a pixel unit and an array substrate of an edge switch mode liquid crystal display device. Background technique [0002] The fringe field switching mode (Fringe Field Switching, FFS) liquid crystal display provides a wide viewing angle liquid crystal device structure, which makes the common electrode and pixel electrode of the pixel on the array substrate, and uses the fringe electric field formed between them to drive the liquid crystal. , has the advantages of wide viewing angle, small color cast, and low power consumption. [0003] The fringe field switching mode liquid crystal display with dual-domain pixel units can have better viewing angle characteristics, and it can still display images well when viewed at a position with a large viewing angle. figure 1 It is a structural schematic diagram of a dual-domain pixel unit of an existing liquid crystal displa...
