Liquid crystal display panel and liquid crystal display device

Abstract

The invention provides a liquid crystal display panel and a liquid crystal display device, comprising a first substrate, a second substrate and a liquid crystal layer, wherein the first substrate and the second substrate are arranged opposite to each other, and the liquid crystal layer is clamped between two substrates, the first substrate comprises a plurality of pixel regions defined by a plurality of scanning lines and a plurality of data lines, and the pixel regions at least comprise a first sub-pixel electrode and a second sub-pixel electrode, a first film transistor and a second film transistor. The first sub-pixel electrode and the second sub-pixel electrode are electrically isolated from each other and the polarities of the first sub-pixel electrode and the second sub-pixel electrode are opposite when the liquid crystal display panel operates; the first sub-pixel electrode and the second sub-pixel electrode are nested with each other, wherein the first sub-pixel electrode is provided with at least one nesting region extending into the second sub-pixel electrode, and the second sub-pixel electrode is provided with at least one nesting region extending into the first sub-pixel electrode. The liquid crystal display panel saves photoetching process of a projection structure and a gap in the process of manufacturing a color filter substrate, simplifies the process, reduces the cost and improves the contrast ratio at the same time.

Description

technical field [0001] The present invention relates to the field of thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD), in particular to a multi-region vertical alignment (Vertical Alignment, VA) liquid crystal display panel and a liquid crystal display device thereof. Background technique [0002] As a flat panel display, liquid crystal display (LCD) has many advantages such as clear and accurate image, thin thickness, light weight, no radiation, low energy consumption and low working voltage, and has been widely used in various fields. Generally, a liquid crystal display has two substrates containing electrodes, and a liquid crystal layer arranged between the two substrates. The electric field intensity applied to the liquid crystal layer is controlled by the electrodes on the two substrates to control the deflection of the liquid crystal molecules, thereby adjusting the intensity of the incident light. Transmittance, in ord...

Problems solved by technology

However, disposing the protrusions 50 on the color filter substrate 80 will generally cause light leakage and reduce the contrast of the liquid crystal display panel. Moreover, it needs to add a photolithography process on the color filter substrate, which makes the manufacturing process complicated and the cost is high.
