TFT-LCD color film / array substrate, liquid crystal display panel and method for producing same

Abstract

The invention relates to a TFT-LCD color film / array baseplate, a liquid crystal display panel and a manufacturing method thereof. The TFT-LCD color film / array baseplate comprises a first baseplate, a color film layer, a transparent layer and an array structural layer, wherein the array structural layer is formed on the transparent layer or another surface of the first baseplate. In the method, the color film structure is formed in the first baseplate; an array structure is formed at any side; the integrated color film / array baseplate is finally formed; and the method prevents that the color film / array baseplate has dislocation and other problems caused by flapping and the like in order to obviously improve the image quality and also reduces contraposition error of box process generated by a color film / array baseplate in the prior process in order that a black matrix and an array of the color film / array baseplate can realize good contraposition, thereby properly reducing the shielding area of the black matrix in design, increasing the aperture ratio of unit pixel, improving the brightness and other properties of a display screen and strengthening the quality of image display of TFT-LCD.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to a TFT-LCD color film / array substrate, a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. [0003] The prior art TFT-LCD includes an array substrate, a color filter substrate, and a liquid crystal material filled between the two substrates. Its working principle is: the electric field between the color filter substrate and the array substrate causes the liquid crystal to rotate, and the electric field strength is adjusted by changing the voltage. The twist and angle of the liquid crystal material can be controlled, thereby controlling the amount of light transmitted in th...

AI Technical Summary

Problems solved by technology

In the manufacturing process of the prior art TFT-LCD, due to the unavoidable existence of a certain range of box alignment deviation in the box alignment process of the color filter substrate and the array substrate, it affects the quality of the TFT-LCD product to a certain extent.

When the deviation of the box alignment exceeds the standard specification, not only the black matrix cannot play a blocking role, but also the RGB color resin will be misaligned, resulting in poor pictures

Even if the deviation of the box alignment is within the allowable range, the misalignment of the color filter and the array substrate will occur during the beating test, causing white areas to appear on the normal screen, resulting in image display defects

According to the process conditions of the existing technology, the deviation of the box alignment can only be controlled at about 7 μm, so in order to prevent the poor black matrix shielding caused by the deviation of the box alignment, the prior art generally adopts the method of appropriately increasing the black matrix shielding area, but this reduces the Aperture ratio per pixel
