Liquid crystal display panel and display device

Abstract

The invention discloses a liquid crystal display panel and a display device. The liquid crystal display panel comprises an opposite direction base plate, an array base plate, a driving circuit and liquid crystals, wherein the opposite direction base plate and the array base plate are in opposite arrangement; the liquid crystals are positioned between the opposite direction base plate and the array base plate; the array base plate is provided with a display region and a non-display region; a signal wire is arranged in the display region; a conversion terminal used for connecting the driving circuit and the signal wire is arranged in the non-display region; a public electrode layer is arranged at one side, facing the array base plate, of the opposite direction base plate; the conversion terminal comprises a first wiring terminal, a second wiring terminal and a conducting layer; the first wiring terminal is electrically connected with the driving circuit; the second wiring terminal is electrically connected with the signal wire; the conducting layer covers the first wiring terminal and the second wiring terminal; the conducting layer and the public electrode layer are in insulation arrangement. The public electrode layer and the conducting layer are in the insulation arrangement, so that current cannot be formed between the public electrode layer and the conducting layer through the crystals to make the conducting layer generate electrochemical corrosion; the situation that the signal transmission cannot be carried out due to open circuit formed between the signal wire and the driving circuit can be prevented, so that the display quality is improved.

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,...

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
