Problems solved by technology
As can be seen from FIG. 2B , there are obvious dark areas near the protrusions 172 in the center and on both sides of FIG. 2B , so that the overall brightness of the multi-domain vertical alignment liquid crystal display panel cannot be further improved.
[0009] In addition, the fabrication of the bumps 172 requires an additional photomask process, which increases the production cost and material cost.
In addition, the liquid crystal molecules located around the protrusions 172 are easily affected by the protrusions 172 and are tilted and arranged, so that the multi-domain vertical alignment type liquid crystal display panel is prone to light leakage in the dark state, resulting in a decrease in contrast.

Embodiment Construction
[0071] FIG. 3 is a partial schematic diagram of a liquid crystal display panel of the present invention. Referring to FIG. 3 , the liquid crystal display panel 200 includes an opposite substrate 210 , an active element array substrate 220 and a liquid crystal layer 230 . The opposite substrate 210 has a common electrode 240 , and the common electrode 240 does not need to have an alignment pattern, and the liquid crystal layer 230 is disposed between the active element array substrate 220 and the opposite substrate 210 . In addition, the active element array substrate 220 has a plurality of scan lines 242 (shown in FIG. 3 ), a plurality of data lines 244 and a plurality of pixels 250, and each pixel 250 is controlled by a corresponding scan line 242 and a data line 244. In this embodiment, only a few pixels 250 in the liquid crystal display panel 200 are shown for illustration.
[0072] FIG. 4 is a partial top view of the liquid crystal display panel in FIG. 3 , and only one p...

Description
technical field [0001] The invention relates to a display device, and in particular to a liquid crystal display panel. Background technique [0002] In recent years, the performance requirements for thin film transistor liquid crystal display (TFT-LCD) are towards high contrast ratio, no gray scale inversion, and little color shift. color shift), high brightness (high luminance), high color richness, high color saturation, fast response and wide viewing angle. [0003] At present, the technologies that can meet the requirement of wide viewing angle include twisted nematic liquid crystal (TN) plus wide viewing film (wide viewing film), in-plane switching (IPS) LCD panel, fringe field switching (fringe field switching (FFS) liquid crystal display panel and multi-domain vertically aligned (multi-domain vertically aligned, MVA) liquid crystal display panel. [0004] For a multi-domain vertical alignment liquid crystal display panel, for example, a plurality of strip-shaped sli...
