  • Publication number: 20210165253
    Abstract: The present invention relates to a liquid crystal display panel and a display device thereof, which removes one of electrodes that forms an electrolytic cell by setting a second electrode layer of the non-display area into a plurality of electrode line segments spaced apart from each other, and also reduces a relative area of the second electrode layer to the first electrode layer, such that electrochemical corrosion of a fan-out area caused by formation of the electrolytic cell can be avoided, and thus the reliability of the product is improved. Since the gap between the electrode line segments of the second electrode layer is filled with the material same as that used for the second polyimide layer, the thickness of the second polyimide layer is increased, such that protection of second the electrode layer is increased, ensuring a normal conversion of the signal and improving the reliability of the product.
