Abstract: A color filter substrate, a liquid crystal panel, a liquid crystal display device and a manufacturing method are provided. The color filter substrate includes a base plate and multiple red color resists on the base plate. Wherein, a thickness of the multiple red color resists at an edge region is greater than a thickness of the multiple red color resists at a center region. In the present invention, a cell gap corresponding to the red color resists at the center region of the liquid crystal panel is greater than a cell gap corresponding to the red color resists at the edge region. Accordingly, the color shift at the edge region of the liquid crystal display panel is compensated to improve a red-shift phenomenon generated at the edge region of the liquid crystal display panel so as to increase the display quality of the liquid crystal display panel.

Abstract: The present disclosure provides a liquid crystal display panel composed of red pixel units, green pixel units and blue pixel units that are arranged in the form of matrix. Every adjacent two rows of pixel units form a pixel-unit group. Polarities of pixel units located at the same column in the same pixel-unit group are the same, and polarities of pixel units located at the same column in adjacent two pixel-unit groups are opposite, thus solving problem of color shift at large viewing angles. Polarities of adjacent red pixel units in each row of pixel units are alternately changed and polarities of adjacent blue pixel units in each row of the pixel units are alternately changed to alleviate grainy effect generated on the entire display image, thereby display effect is greatly enhanced. The present disclosure also provides a liquid crystal display device having the liquid crystal display panel.

Abstract: The present disclosure relates to a pixel structure including a data line, a gate, a pixel electrode, and a common electrode line driving the gate. A capacitor configured between the common electrode line and the pixel electrode is a storage capacitance. The common electrode line and the gate are short-connected. The present disclosure also relates to an operation method of the pixel structures and an array substrate. In view of the above, the driving capability of the common electrode line is enhanced. Second, the WOA trace of the common electrode line may be decreased. Third, the space of the liquid crystal panel may be saved.
