Abstract

The production method for film transistor includes: forming layers in order on the base plate of the premier conducting, the premier dielectric, groove, protection and the premier anti-light etching; then removing the outer ring parts of the premier anti-light etching layer and the protection layer as well as parts of the groove layer; removing all anti-light etching layer; forming interval wall on the side wall of the premier conducting layer and the premier dielectric layer and linking the groove layer; removing the exposed groove layer masked by the patterned protection layer.

Description

technical field [0001] The invention relates to a manufacturing method of a thin film transistor structure, in particular to a manufacturing method of a thin film transistor structure of a liquid crystal display panel. Background technique [0002] In recent years, optoelectronic-related technologies have been continuously introduced, coupled with the arrival of the digital age, which has further promoted the vigorous development of the liquid crystal display market. Liquid crystal displays have the advantages of high image quality, small size, light weight, low driving voltage, and low power consumption, so they are widely used in personal digital assistants (PDAs), mobile phones, video recorders, notebook computers, desktops, etc. Consumer communication or electronic products such as upper-type displays, car displays, and projection TVs are gradually replacing cathode ray tubes and becoming the mainstream of displays. [0003] Liquid Crystal Display (LCD) is a display dev...
