Liquid crystal display panel and manufacturing method thereof

Abstract

The invention provides a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises a TFT substrate and a CF substrate. The TFT substrate includes a first substrate, an intermediate layer, and a BPS layer. The CF substrate includes a second substrate and an organic cover layer. At least one annular trench encircling a display area is arranged in a peripheral area of the BPS layer; a groove that corresponds to the display area and has the surrounding edge extending to the outer side of the display area is formed in the organic cover layer. Therefore, when PI liquid is sprayed on the TFT substrate and the CF substrate, the coating area of the PI liquid is limited to realize control of the precision of the coating of the PI liquid, so that problems of light leakage at the edge of the panel and insufficient adhesion of the frame adhesive are solved.

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] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is very popular because of its advantages of high quality and low price, light weight, easy portability, long service life, clear picture and high reliability. TFT-LCD products can be seen everywhere in our daily life, ranging from commercial advertisements to smart watches. Because of its high reliability, it is also widely used in military industries, such as aerospace and aviation. Although many advanced display modes have emerged, such as organic light-emitting diode (OLED) displays, due to various reasons such as cost, life, reliability, materials, and technical obstacles, they have not been able to replace TFT-LCD. TFT -LCD is still the main force in the current display industry. [0003] Generally, a liquid crystal displ...
