Abstract: An array substrate and a liquid crystal display panel are provided. The array substrate includes sub-pixel groups arranged in an array and each including first and second sub-pixels and a third switch assembly. The first sub-pixel includes a first main-zone electrode, a first sub-zone electrode, and a first switch assembly. The second sub-pixel includes a second main-zone electrode, a second sub-zone electrode, and a second switch assembly. The second switch assembly controls conduction of the second main-zone electrode and the second sub-zone electrode. The third switch assembly is connected to the first and second sub-zone electrodes and controls connection and conduction between the first and second sub-zone electrodes to reduce voltages of the first and second sub-zone electrodes. The array substrate helps reduce the number of switch units involved, simplifies the structure of pixels, lowers down fabrication cost, and also increases an aperture ratio 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: Disclosed is a method for manufacturing a flat liquid crystal display device film. According to the method for manufacturing the flat liquid crystal display device film, influence of a wiring thickness on topography of array film can be reduced. Without affecting a qualified rate of a product, a low-resistance wiring can be realized, and thus an RC delay during signal transmission of a large-sized panel can be reduced. Meanwhile, when the method is applied, a metal layer with a larger thickness relative to that of a metal layer made by a conventional method can be made. Therefore, wiring load of a large-sized panel can be reduced, resistance of signal line can be reduced. RC delay can be decreased, and display quality can be improved.
