Problems solved by technology

In the existing technology, there is a certain precision error in the coating of the frame glue, and the physical state of the frame glue is non-solid. When the upper and lower substrates are pressed together, the frame glue will overflow to both sides, so that the width of the frame glue will increase.
Moreover, when cutting panels, there is also a certain accuracy error. In order to ensure the cutting effect, the frame glue must keep a certain distance from the cutting line to accommodate the accuracy error
However, if the frame glue is far away from the cutting line, the size of the LCD panel will be increased, making the narrow frame design more difficult, and also increasing the requirements for cutting accuracy

Abstract

The invention discloses a liquid crystal panel and a manufacturing method thereof. The liquid crystal panel comprises a first base plate, a second base plate, a frame glue and a retaining wall, wherein the first base plate and the second base plate are oppositely arranged; the frame glue is annularly arranged between the first base plate and the second base plate; the retaining wall is arranged between the first base plate and the second base plate and positioned outside an area surrounded by the frame glue, and the top surface and the bottom surface of the retaining wall respectively closely support against the first base plate and the second base plate. According to the mode, the flush of the frame glue can be avoided and the design difficulty of a narrow frame and the requirement of cutting accuracy can be lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal panel and a manufacturing method thereof. Background technique [0002] In recent years, various display technologies have continued to flourish, and products such as liquid crystal panels have been gradually commercialized and applied to display devices of various sizes. In the process of manufacturing the liquid crystal panel, it generally includes bonding the thin film transistor array substrate and the color filter substrate through a sealant. In the existing technology, there is a certain precision error in the coating of the frame glue, and the physical state of the frame glue is non-solid. When the upper and lower substrates are pressed together, the frame glue will overflow to both sides, so that the width of the frame glue will increase. . Moreover, when cutting panels, there is also a certain accuracy error. In order to ensure the cutting effect, the...
