Problems solved by technology

In the manufacturing process of the photoresist columnar layer, when the photoresist is coated, it is often difficult to control the uniformity, which affects the uniformity and thickness of the columnar layer. Afterwards, the color filter substrate is assembled And the active array substrate also indirectly affects the uniformity of the cell gap (Cell gap)

Embodiment Construction

[0060] see Figure 2A Shown is a dry film according to a preferred embodiment of the present invention, which is mainly used to make a conductive layer of a color filter. The composition of this dry film structure can comprise: bottom layer (Basefilm) 202, be positioned at the antistatic layer 201 on one side of bottom layer 202, be positioned at the photoresist layer 203 on the other side of this bottom layer 202, conductive layer 204 be positioned at the photoresist On the adhesive layer 203 , a flexible auxiliary layer (Cushion layer) 205 is located on the conductive layer 204 and a protection layer (Cover film) 206 is located on the flexible auxiliary layer 205 . It should be noted that the dry film structure of the present invention described here is only an example for the convenience of implementation. In other practical examples, the composition of the dry film structure can be changed or increased or decreased arbitrarily, and is not used to limit the scope of the pre...

Abstract

The invention discloses a dry film and making method and the color filter piece making method, wherein the dry film comprises the following parts: conductive layer, bottom layer and protective layer. The making method of dry film comprises the following steps: forming conductive layer on the bottom layer; forming protective layer on the conductive layer. The making method of color filter piece comprises the following steps: removing the protective layer; stamping the bottom layer and conductive layer on the semi-product of color filter; utilizing the dry film to make the color filter piece.

Description

technical field [0001] The present invention provides a dry film (Dry Film), a method for manufacturing a dry film and a method for manufacturing a color filter (Color Filter), especially provides a dry film structure capable of simplifying the manufacturing process and the manufacture of a color filter method. Background technique [0002] With the rapid development of the computer industry, the production cost and selling price of liquid crystal displays (LCDs) are gradually decreasing. Therefore, how to simplify the manufacturing process and improve the yield of LCDs is an important issue in the industry today. [0003] The components of a liquid crystal display (LCD) mainly include a liquid crystal panel and a backlight module. The backlight module provides light to the liquid crystal panel. The liquid crystal panel includes an active element array substrate, a color filter substrate, and a liquid crystal layer interposed therebetween. [0004] US Patent Publication No....
