A liquid crystal display panel and display device

Abstract

The invention discloses a liquid crystal display panel and a display device, comprising: an opposite substrate and an array substrate, a drive circuit, and a liquid crystal located between the opposite substrate and the array substrate; the array substrate has a display area and a non-display area, The display area is provided with a signal line, and the non-display area is provided with a transfer terminal for connecting the drive circuit and the signal line; the opposite substrate is provided with a common electrode layer on the side facing the array substrate; the transfer terminal includes: electrically connected to the drive circuit The first connection terminal, the second connection terminal electrically connected to the signal line, and the conductive layer covering the first connection terminal and the second connection terminal; the conductive layer is insulated from the common electrode layer. The common electrode layer and the conductive layer are insulated so that no current can be formed between the common electrode layer and the conductive layer through the liquid crystal to cause electrochemical corrosion of the conductive layer, preventing the formation of an open circuit between the signal line and the drive circuit and preventing signal transmission , to improve display quality.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a display device. Background technique [0002] Liquid crystal display panel (LCD, Liquid Crystal Display) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or laptop screen etc. Such as figure 1 As shown, the structure of the liquid crystal display panel is mainly composed of a thin film transistor array substrate 1 (Thin Film Transistor Array Substrate, TFT Array Substrate), a counter substrate 5, a common electrode layer 4 located on the side of the counter substrate 5, and disposed on both sides. The liquid crystal layer 11 (Liquid Crystal Layer) between the substrates is composed of, wherein, the array substrate 1 is provided with pixel electrodes, data lines and gate lines (the pixel electrodes,...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing display panel, since the common electrode layer is an entire layer covering the opposite substrate, there is an area directly opposite the common electrode layer and the conductive layer in the non-display area. There is a voltage difference from the voltage on the common electrode layer, and the electric field formed by the voltage difference will generate a current on the liquid crystal between the common electrode layer and the conductive layer, which will cause the conductive layer to be electrochemically corroded, resulting in poor conductivity or open circuit , the effective transmission of the signal cannot be realized, which affects the display quality
