Abstract

The invention discloses a pixel unit. The pixel unit comprises a first electrode, and a second electrode which forms an electric field with the first electrode; the second electrode comprises upper domain electrodes, lower domain electrodes and an inter-domain electrode; the upper domain electrodes are parallel to each other, and while the lower domain electrodes are parallel to each other; the upper domain electrodes and the lower domain electrodes are distributed in a shape of reversed V without intersecting; each upper domain electrode comprises a first upper domain electrode which is adjacent to the inter-domain electrode; each lower domain electrode comprises a first lower domain electrode adjacent to the inter-domain electrode, the inter-domain electrode is positioned on the wide opening side of a V shaped formed by the upper domain electrodes and the lower domain electrodes, the first upper domain electrodes and the first lower domain electrodes are positioned in 2 to 10 microns away from the narrow opening sides of the reversed V shape. With the adoption of the pixel unit, the problem that liquid crystal cannot deflect normally due to a total electric field at an inter-domain intersecting area in the prior art, which causes decrease of the light transmission rate of a liquid crystal display, can be solved.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal displays, and more specifically relates to a pixel unit. Background technique [0002] FFS (Fringe Field Switching, fringe field switching) mode is a liquid crystal driving mode that can widen the viewing angle. The pixel electrodes in the FFS type TFT-LCD (Thin Film Transistor Liquid Crystal Display, ultra-thin film transistor liquid crystal display) array substrate When power is applied, a horizontal electric field parallel to the substrate is formed between the pixel electrode and the common electrode. Such as figure 1 Shown is a structural plan view of an FFS-type TFT-LCD array substrate in the prior art. Data lines 11 and gate lines 12 are formed on the array substrate. Adjacent gate lines 12 and data lines 11 define pixel areas, and each pixel A thin film transistor (Thin Film Transistor, TFT), a pixel electrode (Pixel Electrode) 13 and a common electrode (Common Electrode) ...
