Problems solved by technology

However, the tilting direction of the liquid crystal molecules located on the edge of the alignment protrusions is difficult to control, and light leakage in the dark state is likely to occur. Therefore, a light-shielding black matrix must be arranged above the alignment protrusions to avoid affecting the display effect of the liquid crystal display panel.
However, the aperture ratio of the liquid crystal display panel is thus reduced. In addition, the scanning lines in the liquid crystal display panel are mostly arranged under the transparent electrodes, which limits the aperture ratio of the liquid crystal display panel.

[0062] In order to disclose the spirit of the present invention in more detail, the structure of the liquid crystal display panel of the second embodiment of the present invention is proposed here.

[0063] FIG. 2A is a schematic top view of a liquid crystal display panel according to a second embodiment of the present invention, and FIG. 2B is a schematic cross-sectional view along line AA' of FIG. 2A . Please refer to FIG. 2A and FIG. 2B at the same time. The liquid crystal display panel 200 of this embodiment is similar to the liquid crystal display panel 100 of the first embodiment, so the same component symbols represent the same meanings, which will not be repeated here. The difference between the two is that there is no need to configure the black matrix 134 for shielding light on the opposite substrate 230 of the liquid crystal display panel 200. In this embodiment, the scanning line 214 on the active device array substrate 210 is designed to have a ring-shaped frame pa...

Abstract

The invention provides a LCD panel, comprising active component array substrate, alignment substrate and liquid crystal layer, where the active component array substrate comprises substrate, multiple scan lines, multiple data lines and multiple pixel cells, where the scan lines and the data lines are arranged on the substrate; the pixel cells are arranged on the substrate and each pixel cell is connected with the corresponding scan and data lines and spans the corresponding scan line; the alignment substrate has multiple alignment bumps, each located above the scan line. Besides, the liquid crystal layer is arranged between the alignment substrate and the active component array substrate. And the invention has better opening ratio and contrast. Besides, the invention reduces the widths of parts of the data lines to make store capacitors able to extend to the data lines so as to further raise the opening ratio of the LCD panel.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, and in particular to a liquid crystal display panel (LIQUID CRYSTAL DISPLAY PANEL) with a high aperture ratio. Background technique [0002] At present, the performance requirements of the market for LCDs are towards high contrast (High ContrastRatio), no grayscale inversion (No Gray Scale Inversion), small color shift (Little Color Shoft), high brightness (High Luminance), and high color richness , high color saturation, fast response and wide viewing angle. At present, there are several technologies that can meet the requirement of wide viewing angle, such as twisted nematic liquid crystal (TN) plus wide viewing film (Wide Viewing Film), in-plane switching (In-plane Switching, IPS) liquid crystal display, marginal field switching Type (Fringe Field Switching) liquid crystal display and multi-domain vertical alignment liquid crystal display. The following will describe the panel of the...
