Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the light-shielding electrode provided on the gate line of the existing pixel structure increases the parasitic capacitance of the gate line, so that the RC delay phenomenon generated on the gate line is serious, affecting the charging rate of the pixel, And the light-shielding electrode is easily affected by the high and low potentials on the gate line, so it will cause side light leakage at the gate line of the curved liquid crystal display

Abstract

The invention discloses a pixel structure and a liquid crystal display panel. The pixel structure includes a substrate, a first metallic layer, a first insulation layer and a transparent electrode layer; the first metallic layer is formed on the substrate, and includes patterns of gate lines; the first insulation layer is formed on the first metallic layer; the transparent electrode layer is formed on the first insulation layer; the transparent electrode layer includes first transparent electrodes; projections of the first transparent electrodes on the gate lines are positioned in local regions of the gate lines, i.e., parts corresponding to the gate lines, of the first transparent electrodes do not completely cover the gate lines. The liquid crystal display panel is a liquid crystal display screen having the pixel structure. The pixel structure can reduce the RC load of the gate lines, the voltage provided by the gate lines is more stable, and influence on the pixel charging rate is reduced. Influence of high-low potential generated by the powered-on gate lines on the transparent electrodes is reduced, lateral light leakage of the gate lines of the pixel structure is avoided, the aperture opening ratio of pixels is improved, and the display quality of the liquid crystal display screen having the pixel structure is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel structure and a liquid crystal display panel with the pixel structure. Background technique [0002] The PSVA (Polmer Stabilized Vertically Aligned, polymer stabilized vertically aligned liquid crystal) mode liquid crystal display uses a vertical electric field in the vertical direction to drive the liquid crystal molecules vertically arranged on the glass substrate, thereby forming a polymer stabilized and vertically aligned liquid crystal. display screen. The liquid crystal display in this mode is in a black display state when no voltage is applied; after a certain voltage is applied, the liquid crystal molecules of the liquid crystal display fall to the horizontal direction, and the liquid crystal display in this mode is in a white display state. [0003] At present, in order to avoid the side light leakage of the liquid crystal display screen caused by the bending o...
