Embodiment Construction

[0018] see image 3 , is a schematic diagram of the first embodiment of the manufacturing method of the color filter of the present invention. First, make a first base layer 34; then make a black resin matrix layer 33 on the surface of the first base layer 34, the material of this black resin matrix layer 33 is black photosensitive resin or black thermal resin, also available phenolic resin or acrylic Resin and black pigment are mixed; Then a coloring layer 32 is formed on the surface of the first base layer 34, and the coloring layer 32 includes three kinds of coloring units of red (R), green (G) and blue (B), and its function is The light is filtered so that it only passes through the light of the same color as the coloring unit; the coloring unit and the black resin matrix layer 33 are alternately distributed on the first base layer 34 . Parts 321 and 322 of the colored layer 32 extend to the entire surface of the black resin matrix layer 33 to cover the black resin matrix...

Abstract

Method for fabricating color filter includes following steps: preparing first base layer; preparing a black resin matrix layer on surface of the first base layer; forming a chromatic layer on surface of the first base layer, the chromatic layer and the black resin matrix layer are distributed on the first base layer alternately, and part of the chromatic layer is extended to whole surface of the black resin matrix layer.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of a color filter and a manufacturing method of a liquid crystal display device. 【Background technique】 [0002] The liquid crystal display device is a passive display device. In order to achieve the effect of color display, it is necessary to provide a color filter for it. Its function is to provide color for the liquid crystal display device. Different color images are displayed by other components such as liquid crystals. [0003] see figure 1 , is a schematic diagram of a prior art color filter manufacturing method. The manufacturing method of the color filter 20 includes: making a glass substrate 24; forming a black matrix 23 on the surface of the glass substrate 24; ) and green (G) three coloring units; then, a transparent ITO (Indium Tin Oxide, indium tin oxide) layer 21 is formed on the surface of the coloring layer 22 . The glass substrate 24 serves as a carrier for the above-mentioned comp...
