The invention provides a liquid crystal display panel comprising a first substrate, a second substrate arranged opposite to the first substrate and a liquid crystal layer arranged between the first substrate and the second substrate, wherein a common electrode is arranged between the first substrate and the liquid crystal layer, and a black matrix electric-conducting ring for shielding the common electrode, a grounding part arranged on the second substrate and an electric-conducting structure for connecting the black matrix electric-conducting ring and the grounding part are formed on the liquid crystal display panel. When external high-voltage static electricity is applied to the liquid crystal display panel, the black matrix electric-conducting ring discharges the external high-voltage static electricity through the annular grounding part of the lower substrate, and induced charges generated by external high-voltage static electricity are released at the same time. Therefore, high-intensity current generated by the high-voltage static electricity and strong current triggered by the induced charges are prevented from being transmitted to an integrated circuit to burn down the integrated circuit, the normal display of the liquid crystal display panel is guaranteed, the reliability of the liquid crystal display panel is improved and the service life of the liquid crystal display panel is prolonged.
Description
technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel with an antistatic structure and a manufacturing method thereof. Background technique [0002] Liquid Crystal Displays (LCDs) have been widely used in products such as televisions, notebook computers, mobile phones, and personal digital assistants due to their thin and light appearance, low power consumption, and no radiation pollution. A liquid crystal display panel is a key component of a liquid crystal display device, and it mainly includes two substrates and a liquid crystal (LC) encapsulated between the two substrates with a sealant. The principle of liquid crystal display is to apply a voltage to the above two substrates and form an electric field between the above two substrates. Under the action of the electric field, liquid crystal molecules rotate and control the passage of light beams to display images. [0003] Such as figure 1 As...
