Problems solved by technology

However, the problem with this solution is that the thickness of the passivation layer needs to be more than 2 microns (μm), so that the parasitic capacitance can be reduced to meet the requirements when the distance between the pixel e

Abstract

The invention relates to a liquid crystal panel and a manufacturing method thereof. The liquid crystal panel comprises two display substrates capable of being perfectly bonded together, wherein raster scanning lines and data lines are formed on the first display substrate, and enclose to form a pixel unit; a thin film transistor (TFT) is arranged in the pixel unit; a pixel electrode and a common electrode are respectively formed in each pixel area of the second lining substrate; a first pad object containing a conducting material is formed between the first display substrate and the second display substrate, and connects the pixel electrode on the second display substrate and a drain electrode exposed through a first hole; and a common electrode line is formed on the first lining substrate or the second lining substrate, and is electrically connected with the common electrodes. A technical means of separately arranging the pixel electrodes and the common electrodes forming a horizontal field and the data lines on the two display substrates is adopted, and the parasitic capacitance between the pixel electrodes and the data lines cannot be improved when adjacent pixel electrodes are close to each other.

Description
