Problems solved by technology

Limited by the border width of the liquid crystal display panel, the width of the metal wiring on the TFT substrate can only be designed to be very narrow. The risk of light leakage cannot be completely blocked, so there may be risks such as red lines on the edges of the LCD panel and a drop in yield rate

Abstract

The invention provides a liquid crystal display panel. The panel comprises an array substrate, a color film substrate, a liquid crystal layer and bezel glue, after the two substrates are assembled, adisplay area and a non-display area are correspondingly formed, the liquid crystal is located between the two substrates, and a closed area enclosed by the bezel glue is filled with the liquid crystallayer; at least two first metal lines are formed on the non-display area of the array substrate and used for shielding leakage light of a BM groove formed in the side, close to the liquid crystal layer, of the non-display area of the color film substrate; the array substrate further comprises a shading plate, the shading plate is arranged in the non-display area of the array substrate and locatedbelow the two first metal lines, and the length of the shading plate is greater than or equal to the spacing between the two first metal lines to eliminate the phenomenon of edge red lines occurringon the BM groove. By utilizing the liquid crystal display panel, the shading plate is additionally arranged in the non-display area of the array substrate and located below the metal lines used for shielding the leakage light of the BM groove of the color film substrate to eliminate the phenomenon of edge red lines, and the product yield is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel. Background technique [0002] The structure of the liquid crystal display panel is mainly composed of a thin film transistor array (Thin Film TransistorArray, TFT Array) substrate, a color filter (Color Filter, CF) substrate, and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. Its working principle is to control the rotation of the liquid crystal molecules in the liquid crystal layer by applying a driving voltage on the two substrates, and refract the light from the backlight module to generate a picture. [0003] like figure 1 As shown, the LCD panel 10 / In order to prevent electrostatic (ESD) damage during the process, it will be displayed on the display area AA / around (i.e. non-display area BB / ) design multiple BM (black matrix) slots 201 / , the BM slotting 201 / Set on the non-displa...
