Abstract

The invention provides a display panel and a display device. The display device comprises a display panel, wherein the display panel comprises a first substrate, a first electrostatic shielding layer,a liquid crystal layer, a second substrate, a second electrostatic shielding layer and a conducting resin layer, which are stacked together. The liquid crystal layer is sandwiched between the first electrostatic shielding layer and the second electrostatic shielding layer; one end of the conducting resin layer is electrically connected to the first electrostatic shielding layer, and the other endthereof is electrically connected to the second electrostatic shielding layer for shielding the interference of an external electric field on the liquid crystal layer. According to the display deviceprovided by the invention, by using the electrostatic shielding principle of a Faraday cage, respectively disposing the first electrostatic shielding layer and the second electrostatic shielding layer on the upper and lower sides of the liquid crystal layer and electrically connecting the two electrostatic shielding layers through the conducting resin layer, an electrostatic shielding cage is formed and grounded, thereby eliminating the interference of the external electric field on the liquid crystal molecules of the liquid crystal layer and ensuring the quality of image display.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] In the field of liquid crystal display technology, liquid crystal display devices (Liquid Crystal Display, LCD) have been widely used in televisions, notebook computers, mobile phones, personal digital assistants, etc. product. [0003] For liquid crystal display devices, especially in-plane switching (IPS) and fringe field switching (FFS) display modes, they are easily disturbed by external electric fields during use, resulting in degradation of image quality or even failure. It is very important for LCD display devices. [0004] like figure 1 , figure 2 As shown, the liquid crystal display panel 90 in the prior art includes a first substrate 91 , a pixel electrode layer 92 , a liquid crystal layer 93 , a second substrate 94 , an electrostatic shielding layer 95 , a ground terminal 96 and a conductive silver pas...
