Embodiment Construction

[0030] In order to overcome the problem of high production cost of the color filter in the prior art, the present invention saves the process of making a transparent conductive layer by adding a conductive material to the protective layer. Furthermore, there is no need for professional equipment required for manufacturing the transparent conductive layer and raw materials required for manufacturing the transparent conductive layer, which is beneficial to save costs. At the same time, the process for manufacturing the color filter omits the process of making the transparent conductive layer, which saves the time required for producing a single color filter and is beneficial to improving the production efficiency of the color filter. Therefore, the color filter and the manufacturing method thereof provided by the present invention can effectively save production cost and improve production efficiency at the same time.

[0031] The color filter provided by the present invention a...

Abstract

The invention relates to the technical field of flat panel display, particularly to a color filter of a liquid crystal display and a manufacturing method thereof. The color filter comprises a base plate, a shading region, a colored film and a protective layer. The protective layer comprises conducting material and is used as a public electrode of the color filter, therefore, a transparent conducting layer in the prior art is not needed any longer, the production cost of the color filter is reduced, and the production efficiency of the color filter is improved. In addition, the invention also provides a manufacturing method of the color filter.

Description

technical field [0001] The invention relates to the technical field of flat panel display, in particular to a color filter of a liquid crystal display and a manufacturing method thereof. Background technique [0002] Liquid Crystal Display (LCD for short) has the advantages of small size, low power consumption, and no radiation, so it gradually replaces the traditional CRT (Cathode Ray Tube, CRT for short) display, and has become the first choice for people to choose flat panel display devices. prior choice. In recent years, liquid crystal displays have achieved rapid development, whether it is screen size or display quality, great progress has been made. [0003] As the demand for liquid crystal displays increases day by day, many manufacturers have also joined the army of producing liquid crystal displays. Faced with a limited market, the competition among manufacturers is becoming increasingly fierce. While improving product performance, manufacturers are also working ...
