Abstract

A color filtering substrate is prepared as setting color filtering patterns on substrate; setting back matrix layer on substrate and placing it between color filtering patterns; setting interval substance on black matrix layer and connecting it with black matrix layer; setting convex structure on those color filtering patterns and forming black matrix layer, interval substance and convex structure by the same material; using shared electrode to cover color filtering pattern, black matrix layer, convex structure and interval substance.

Description

technical field [0001] The invention relates to a filter device and its manufacturing method, and in particular to a color filter substrate and its manufacturing method. Background technique [0002] Due to the increasing demand for displays, the industry is fully committed to the development of related displays. Among them, the cathode ray tube (cathode ray tube, CRT) has been monopolizing the display market for many years because of its excellent display quality and technological maturity. However, due to the rise of the concept of green environmental protection recently, based on the characteristics of large energy consumption and large radiation generated by cathode ray tubes, and the limited space for flattening their products, cathode ray tubes cannot meet the market demand for light, thin, short , small, beautiful and low power consumption market demand. Therefore, thin film transistor liquid crystal displays (thin film transistor liquid crystal displays, TFT-LCDs),...
