Abstract

The invention discloses an LTPS (Low Temperature Poly-Silicon) array substrate and a liquid crystal display panel. The LTPS array substrate comprises a first common electrode layer, a passivating layer, a pixel electrode layer and a second common electrode layer, wherein the passivating layer is formed on the first common electrode layer, and a first via hole is formed in the passivating layer; the pixel electrode layer is formed on the passivating layer; the second common electrode layer formed on the passivating layer is positioned between pixel electrodes of two adjacent subpixels in the pixel electrode layer and is electrically isolated from the pixel electrode layer, and the second common electrode layer is electrically connected with the first common electrode layer through the first via hole. According to the array substrate, the electric field intensity at the marginal area of the adjacent subpixels can be obviously enhanced, and then the penetration rate at the area is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an LTPS array substrate and a liquid crystal display panel. Background technique [0002] Low Temperature Poly-Silicon (LTPS) thin film transistor liquid crystal display (LTPS-TFTLD) is different from traditional amorphous silicon thin film transistor liquid crystal display, which has high resolution, fast response speed, high brightness and high aperture ratio. Advantages, therefore, LTPS-TFTLD has been more and more widely used. [0003] However, the existing LTPS-TFTLD array substrate has the problem that the transmittance at the edge of adjacent sub-pixels is significantly lower than that at other positions, which affects the display effect of the liquid crystal display panel. [0004] Based on the above situation, there is an urgent need for an LTPS array substrate capable of ensuring the transmittance at the edge positions of adjacent sub-pixels. Contents ...
