Abstract

The invention provides an array substrate and a liquid crystal display panel. The array substrate comprises data lines, scanning lines, shared electrode lines and pixels, and the plurality of data lines are distributed at intervals along the vertical direction. The plurality of scanning lines are distributed at intervals along the horizontal direction. The shared electrode lines are parallel to the data lines and located between the adjacent data lines. The plurality of pixels are distributed in an array, and each pixel comprises a first sub-pixel, a second sub-pixel and a third sub-pixel. Inthe pixels, shielding electrodes are arranged in a first area correspondingly close to the data lines, a second area close to the scanning lines, a third area where the shared electrode lines are located and a fourth area between the adjacent rows of pixels, and the setting density of the shielding electrodes corresponding to the first sub-pixels is smaller than that of the shielding electrodes corresponding to the third sub-pixels. By reducing the density of the shielding electrodes in the first sub-pixels, the dark state light leakage phenomenon of the liquid crystal display panel is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] Shielding electrodes are used in existing liquid crystal display panels to shield the influence of data lines on pixel electrodes. However, due to limited process conditions, the cross-section of the shielding electrodes after etching has a trapezoidal structure, and the extending direction of the sides of the trapezoid is consistent with the polarization of the polarizer. The axis is at a certain angle, so that light leakage occurs in the dark state, which affects the display effect. This is especially obvious when the shielding electrode traces are bent and crossed at right angles. [0003] Therefore, the existing liquid crystal display panel has the technical problem of light leakage in the dark state, and in addition to the adjustment of process and film quality, structural design improveme...
