Abstract

The invention provides a display panel. The display panel includes an array substrate and a colorful filter substrate; the colorful filter substrate comprises color resistors and a black matrix; an extension area is arranged between the periphery of each color resistor and the black matrix, and is internally provided with first insulating electrodes made of conductive materials; the array substrate comprises pixel electrodes corresponding to the color resistors in a one-to-one mode, the outer circumference of each pixel electrode is provided with a circle of second insulating electrodes opposite to the first insulating electrodes in position, and the second insulating electrodes are not in contact with the pixel electrodes; the voltage applied on the first insulating electrodes is equal tothat applied on the second insulating electrodes. The invention further provides a manufacturing method of the display panel. Compared with the prior art, the occurrence of aligning dark fringes at the edges of the pixel electrodes is reduced.

Description

technical field [0001] The invention relates to a liquid crystal panel technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] At present, a liquid crystal display panel usually includes a color filter substrate (CF substrate), an array substrate (TFT substrate), and a liquid crystal (LC) filled between the color filter substrate and the array substrate to form a liquid crystal cell, in which PSVA (PolmerStabilized Vertically Aligned (polymer stabilized vertically aligned liquid crystal) display mode, as a PSA technology, has the advantages of high contrast, wide viewing angle, fast response and low power consumption. It is one of the display modes used by mainstream liquid crystal display panels at present; The principle is that, firstly, a power source is used to deflect the liquid crystal molecules, and then anchored by ultraviolet light (UV) to complete the alignment of the liquid crystals. In the PSVA production pr...
