Problems solved by technology
[0008] 1. The liquid crystal molecules corresponding to the intersection of the second common electrode 240 (the intersection of the vertical electrode 241 and the horizontal electrode 242) are easy to knot, and the electric field corresponding to the intersection in the liquid crystal display panel controls the liquid crystal molecules force difference;
[0009] 2. On the thin film transistor substrate 200, a via hole needs to be provided on the outside of the corresponding pixel electrode 230, so that the second common electrode 240 is connected to the lead wire of the second external common electrode, thereby increasing the area of the non-pixel area in the liquid crystal display panel, thereby reducing the The number of pixels per unit area on the LCD panel is not conducive to the realization of high resolution of the LCD panel

The invention provides a liquid crystal display panel and a manufacturing method thereof. Second expanded portions with arc edges are arranged at crisscross positions of second common electrodes to change electric field curves at the crisscross positions and enhance control power of electric fields to liquid crystal molecules at the crisscross positions, and accordingly pixel liquid crystal efficiency can be improved; in addition, second common electrode leads are arranged below the second common electrodes, insulation layers between the second common electrodes and the second common electrode leads are provided with through holes, and consequently the second common electrodes and the second common electrode leads are connected, and the problem of connection of the common electrodes to external common electrode leads is solved. By the improvements, application of vertical alignment type liquid crystal display panels to small-size high-resolution panels is broadened. The manufacturing method of the liquid crystal display panel is simple in process, and the manufactured liquid crystal display panel is high in display quality and easy to realize high resolution.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] Liquid crystal displays have become display terminals in mobile communication devices, notebook computers (PCs), and televisions (TVs) due to their advantages of high display quality, low price, and portability. The liquid crystal display commonly used at present usually consists of upper and lower substrates and a middle liquid crystal layer, and the substrate is composed of glass and electrodes. If electrodes are provided on the upper and lower substrates, a display in a longitudinal electric field mode can be formed, such as a twisted nematic (TN, Twist Nematic) mode, a vertical alignment (VA, Vertical Alignment) mode, and a multi-quadrant vertical alignment developed to solve a narrow viewing angle. Mode (MVA, Multidomain Vertical Alignment). Another type of display is differen...
