Color filter and manufacturing method thereof

Abstract

The invention provides a color filter and a manufacturing method thereof. The manufacturing method of the color filter comprises the following steps: pressing a black matrix micro embossed pattern on a black matrix elastic stamp onto a substrate, and transferring the black sol on the black matrix micro embossed pattern onto the substrate to form a black matrix; pressing a color resistance micro embossed pattern on a color resistance elastic stamp onto the black matrix substrate, and transferring the color sol on the color resistance micro embossed pattern onto the substrate to form a color resistance. According to the color filter and the manufacturing method thereof of the invention embodiment, a black matrix elastic stamp and a color resistance elastic stamp are used respectively to form a black matrix and a color resistance on a substrate, which substitutes the gluing, exposure and developing process in the prior art, solves the problem in the prior art that color filters have low manufacture efficiency and high cost, simplifies process steps, and reduces cost; and the boundary of the color resistance pattern in the obtained color filter is clear, and the precision is increased.

Description

technical field [0001] The embodiments of the present invention relate to liquid crystal display manufacturing technology, in particular to a color filter and a manufacturing method thereof. Background technique [0002] The working principle of Thin film Transistor-Liquid Crystal Display (TFT-LCD) is to use the electric field to control the state of liquid crystal molecules, so as to control the light generated by the backlight to pass through the liquid crystal molecules, and then pass through the various elements in the color filter. Color-resistive, displaying color patterns on the display. The color filter is one of the basic components of TFT-LCD. It is composed of red, green and blue pixels, which are arranged on the substrate in a pattern or array to achieve a colorful visual perception. The manufacturing method of the color filter in the prior art mainly includes: using the methods of gluing, exposing and developing to form a black matrix and color resist on the su...
