Abstract: An array substrate and a display panel are disclosed. In the array substrate, array electrodes of at least a portion of pixel units that are adjacent to a base plate edge have areas that are gradually decreased from a base plate center toward the base plate edge. The portion of the array electrodes gradually decreased are arranged in a region of a display panel in which the brightness is relatively bright. If the areas of the array electrodes are decreased, the aperture ratios of the pixel units are reduced. After the aperture ratios of the pixel units are reduced, light transmission rate in an edge zone of the array substrate can be lowered. As such, the portion of the base plate edge of which light is relatively bright is made corresponding to the brightness of the base plate center, thereby realizing the improvement on the nonuniformity of periphery displaying.

Abstract: The present disclosure discloses a liquid crystal display (LCD) panel and a display device. Two thin film transistors (TFT) are disposed in a sub-pixel of the LCD panel. A quantity of the TFTs is reduced, and an aperture ratio of the pixel is increased. A third capacitor is connected in series between a TFT in a sub-area and a liquid crystal capacitor in the sub-area. A voltage of the sub-area declines with an increase in capacitors. Therefore, a deflection angle of liquid crystal molecules in a main area is greater than a deflection angle of liquid crystal molecules in the sub-area, forming different viewing angles. In this way, a color shift is resolved.
