Thin-film transistor substrate, manufacturing method thereof and display panel

Abstract

The invention provides a thin-film transistor substrate, a manufacturing method thereof and a display panel provided with the thin-film transistor substrate. The display panel includes a thin-film transistor substrate, an opposite substrate arranged opposite to the thin-film transistor substrate, and a liquid crystal layer sandwiched between the thin-film transistor substrate and the opposite substrate. According to the technical scheme of the display panel, a color filter layer is formed on the thin-film transistor substrate. Meanwhile, a positive photoresist and a negative photoresist are cooperatively used at the same time. In this way, the prepared color filter layer has small-size contact holes. Therefore, the thickness of the display panel is effectively reduced and the defects of light leakage, lower permeability and the like, caused by alignment deviation, are reduced. At the same time, the resolution of the display panel is increased and the display effect of the display panel is improved.

Description

technical field [0001] The invention relates to a thin film transistor substrate, its manufacturing method and a display panel with the thin film transistor substrate. Background technique [0002] Displays are now widely used in various display fields, such as households, public places, office places and personal electronic related products. To develop in a higher direction. At present, liquid crystal display devices have developed from Twisted Nematic (TN) liquid crystal displays with simple fabrication, low cost and small viewing angle to multi-dimensional electric field (Advanced SuperDimension Switch, AD-SDS, referred to as ADS) liquid crystal display devices, and based on The HADS type liquid crystal display device of the high aperture ratio that ADS mode proposes, no matter which kind of liquid crystal display device, the manufacture technology of its liquid crystal display panel all is to manufacture thin-film transistor array substrate and color filter substrate se...

AI Technical Summary

Problems solved by technology

[0003] Since the thin film transistor array substrate and the color filter substrate are manufactured independently and then aligned into a box together, there will be at least two thicknesses of the substrates. At the same time, there is an alignment deviation when the two substrates are aligned. It will lead to defects such as light leakage and lower transmittance; moreover, with the increase in the resolution of end products, when the resolution of small and medium-sized products is increased to 500ppi or even higher, it is difficult to make the contact on the color filter with the existing technology. The size of the hole can meet the requirements of less than 5um or even smaller
