Liquid crystal display panel and production method thereof

Abstract

The invention provides a liquid crystal display panel and a production method thereof. The liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer clamped between the first substrate and the second substrate. The first substrate is a thin film transistor array substrate, and the second substrate is a colored optical filter substrate. Photosensitive materials containing silver halides are coated on the first substrate and the second substrate, and are subject to exposure processing through light interference fringes, and silver grates in stripe arrays are formed on the first substrate and the second substrate. The liquid crystal display panel includes the first substrate and the second substrate which are provided with polarization structures, the photosensitive materials are subject to exposure processing by aid of the light interference fringes through the polarization structures, and accordingly the silver grates in stripe arrays are formed on the first substrate and the second substrate. The liquid crystal display panel omits polaroids so the adverse effects caused by attachment of polaroids can be avoided. Meanwhile, the process is simplified and cost is reduced by omitting the procedure of attaching polaroids.

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 Display (LCD) has the advantages of good picture quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and currently occupies a dominant position in the display field. Liquid crystal displays are ideally suited for use in desktop computers, palmtop computers, personal digital assistants (Personal Digital Assistant, PDA), cellular phones, televisions, and a variety of office automation and audio-visual equipment. [0003] The LCD panel is the main component of a liquid crystal display. A commonly used LCD panel is composed of a thin film transistor (Thin Film Transistor, TFT) array substrate, a color filter (Color Filter, CF) substrate, and liquid crystal molecules sandwiched between the two su...

AI Technical Summary

Problems solved by technology

[0005] Since the existing polarizing plate is formed by laminating multilayer film materials, when laminating such as PVA 103 and first TAC 102 between multilayer film materials, it is easy to mix foreign matter such as dust etc. and cause damage to the LCD panel. Display Error

In addition, due to its physical properties, the PVA 103 in the existing polarizer is easy to shrink in a high-temperature and high-humidity environment, and it is easy to cause abnormal display of the LCD panel, such as light leakage on the left and right sides (also known as Butterfly Mura).
