Description

technical field

[0001] The invention relates to a method for reducing light leakage in a light-shielding area, in particular to a method for reducing light leakage in a light-shielding area used in a liquid crystal display device and a liquid crystal display panel. Background technique

[0002] With the gradual maturity of liquid crystal display (Liquid Crystal Display, LCD) technology, it has gradually replaced the traditional display technology using cathode ray tube (Cathode Ray Tube, CRT), and is widely used in various electronic products. Among them, liquid crystal display panels can be divided into in-plane switching (InPlane Switching, IPS) type, multi-domain vertical alignment (Multi-domain Vertical Alignment, MVA) type, twisted nematic (TwistNematic, TN) type, color filter and thin film transistor array (ColorfilterOnArray, COA) type or semi-transflective type (Transflective), etc. Herein, a COA type liquid crystal display panel will be used as an example for illus...
