Liquid crystal panel and display device

Abstract

The invention discloses a liquid crystal panel and a display device, used to improve ESD phenomenon of a display device and improve quality of the product. The liquid crystal panel comprises an array substrate and a color film substrate which are aligned through frame sealing glue. The color film substrate comprises an electrostatic shielding layer and a black matrix which is in the electrostatic shielding layer and is close to a side of the array substrate. The surrounding region of the black matrix is provided with an annular channel whose position is opposite to the frame sealing glue. In the technical scheme of the embodiment, since the surrounding region of the black matrix is provided with the annular channel whose position is opposite to the frame sealing glue, when external static electricity enters, the static electricity can just reach the portion of the black matrix, on the outer side portion of the annular channel, and cannot reach an internal display region. Compared with the prior art, the liquid crystal panel and the display device can reduce defects of bubbles, broken lines, or green display, etc., and improve ESD phenomenon of the display device, and improve quality of products.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal panel and a display device. Background technique [0002] Among the flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, no radiation and relatively low manufacturing cost, and occupies a dominant position in the current flat panel display market. [0003] In semiconductor devices, ESD (ElectroStatic Discharge, ESD for short) is a common phenomenon. ESD can cause breakdown of the insulating medium, thereby causing threshold voltage drift or short circuit between the gate electrode and the source and drain levels. At present, an electrostatic shielding layer is usually installed between the base substrate of the color filter substrate and the polarizer. When the external static electricity touches the screen, the electrostatic shielding layer can quickly guide the static electricity into the grou...

Problems solved by technology

[0004] However, the inventors of the present application found that when using an electrostatic gun to test the reliability of the LCD panel, there will still be a large amount of electrostatic charge accumulated on the black matrix inside the LCD panel, which will cause bubbles, disconnection or display of the LCD panel. Defects such as greening will seriously affect the quality of the product
