Problems solved by technology

[0004] Although the existing dual-domain structure can improve the viewing angle, there is a defect: at the junction of the two domains in the pixel area, such as figure 1 At the position indicated by the reference numeral 12, the liquid crystal cannot rotate due to the electric field formed by the pixel electrodes in the two domain regions in the vertical direction with the same magnitude and opposite direction, so the liquid crystal cannot rotate. Therefore, the position indicated by the reference numeral 12 The liquid crystal cannot play the role of changing the polarization direction of the linearly polarized light, and eventually the light source cannot pass through the upper polarizer at all gray levels except the zero-level gray level, that is, at the position indicated by reference numeral 12 will produce a black line
exist figure 2 shows the disclination phenomenon of the existing dual-domain pixel region, such as figure 2 As shown, the junction region of the two domain regions has a certain area of ​​black region (dislocation region), and the light transmittance of the liquid crystal display decreases

According to the TFT array substrate, the liquid crystal display panel and the liquid crystal display, the area of the disclination area in a double-domain structure of the IPS and FFS mode is reduced, the display performance of the double-domain structure is improved, and the light penetration rate of the liquid crystal display is improved.

Description

technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to the field of array substrate structure technology, in particular to a TFT array substrate, a liquid crystal display panel and a liquid crystal display. Background technique [0002] IPS (In-Plane Switching, in-plane switching) mode and FFS (Fringe Field Switching, fringe field switching) mode liquid crystal display provide a liquid crystal device structure with a wide viewing angle, and the pixel electrode and the common electrode are arranged on the same substrate. The liquid crystal is driven by generating a transverse electric field force to change the orientation angle of the optical axis of the liquid crystal molecules in a plane parallel to the substrate. Among them, the single domain (one domain) technology in IPS and FFS modes is widely used due to its advantages of wide viewing angle, small color shift, and low power consumption. However, as user...
