Depend on Figure 2B It can be seen that at Figure 2B Obvious dark areas appear in the center of the center and near the protrusions 172 on both sides, 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.

Abstract
The utility model relates to a liquid crystal display (LCD) panel and pixel. The LCD panel comprises an opposed substrate, an active element array substrate and a liquid crystal layer. The opposed substrate is provided with a shared electrode; the active element array substrate is provided with a plurality of scanning beams, a plurality of data lines and a plurality of pixels; wherein each pixel is controlled through the corresponding scanning beam and data line, and each pixel comprises an active element, a first pixel electrode, a dielectric layer and a second pixel electrode. The first pixel electrode is provided with a first slit and is connected electrically with the active element. The dielectric layer covers the first pixel electrode. The second pixel electrode is provided with a second slit and is arranged between the dielectric layer and the symmetrical substrate; the second pixel electrode is connected electrically with the first pixel electrode; the first slit and the second slit are substantially aligned with each other, and the width of the first slit is smaller than the width of the second slit. The utility model enables wide view angle display and improves display quality.
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...
