Abstract

The invention relates to an array substrate and a manufacturing method thereof and a liquid crystal panel and a manufacturing method thereof. The array substrate comprises a display area and a non-display area, wherein the non-display area comprises a cutting area and other areas, the other areas are provided with a double-layer structure which is formed by a grid insulation film and a passivation film, and the cutting area exposes the substrate. During the cutting process, the defects such as the breakage or fracture of the grid insulation film and the passivation film can be effectively overcome.

Description

technical field [0001] The invention belongs to the field of liquid crystal display devices, and in particular relates to an array substrate and a manufacturing method thereof, a liquid crystal panel and a manufacturing method capable of preventing damage or cracking of a gate insulating film and a passivation film during a cutting process. Background technique [0002] A liquid crystal display device (Liquid Crystal Display, referred to as LCD) is a main flat panel display device (Flat Panel Display, referred to as FPD). [0003] Liquid crystal display devices are classified into vertical electric field type liquid crystal display devices and horizontal electric field type liquid crystal display devices according to the direction of an electric field for driving liquid crystals. Vertical electric field type liquid crystal display devices include: twisted nematic (TwistNematic, referred to as TN) type liquid crystal display devices; horizontal electric field type liquid crys...
