Description of the invention (1) Field of the invention The present invention relates to a dry film of a scattered layer, which is a process for manufacturing a color-filter by a dry film transfer method. In the dry film provided by the present invention, the scattered layer in the color filter can be manufactured by the dry film transfer method. BACKGROUND OF THE INVENTION With the rapid development of the computer industry, the technology of various monitors is constantly changing. The production cost and selling price of liquid crystal displays (LCDs) have also gradually decreased, and their use has become increasingly widespread. Compared with traditional cathode ray tube (CRT) screens, LCDs have many advantages such as low power consumption, small size, light weight, and no radiation. Therefore, in addition to notebook computers, the proportion of desktop computers using LCDs has recently Also gradually increased. But so far, the power consumption of LCD backlights is still relatively high for portable applications. Therefore, in order to further expand the market demand, manufacturers engaged in LCD production have made every effort to reduce their power consumption. This way, the reflective LCD without the need for a backlight (backlight) has become one of the focus of the competition. Currently, the most widely used reflective LCDs in the market are mainly divided into TFT LCD and STN LCD. In short, TFT LCD roughly includes a TFT array glass and a color-filter (CF) part. STN The LCD panel 1J includes an ITO pattern glass portion and a color-filter (CF) portion, and is filled with liquid crystal between two layers of glass. Among them, as shown in FIG. 1, the color filter part includes a glass substrate 10, the surface of which is covered with a sheet of paper 4. The paper size is applicable to the Chinese National Standard (CNS) A4 grid (210X 297 mm) (Please read first Note on the back ^ Write this page) Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 554217 A7 B7 V. Description of the invention The pixel array (pixeh) formed by the three colors is 1 2 ', and above it, it is usually necessary to set another one containing diffuse particles 1 4 (diffuser) <cover layer! 6 (〇ver c〇at) to scatter light and increase The LCDi can be viewed. As for the surface of the cover layer 16, it is usually covered with a layer of transparent electrode film 18, as is well known in the industry, as a common electrode of the color filter. The existing manufacturing method of the color filter, It can be roughly divided into two types: spin coating method and dry film lamination method. After the pixel array 12 of the color filter is manufactured, the cover layer 16 on the pixel array 12 is rotated to the coating layer. In a way that will contain scattered particles 1 4 of the material The Han is attached to the pixel array 12. However, the process of setting a cover layer by spin coating is difficult, the yield is low, and the control of its thickness uniformity is not easy, and it needs to be further improved. The purpose is to provide a dry film containing scattered particles for the color filter manufacturing process, so that the scattered layer can be arranged on the pixel array of the color filter by dry film transfer. The main technical content of the present invention is printed by the Consumer Bureau of Standards Bureau. In order to provide a dry film with scattered layers, it is used in the process of manufacturing a color filter by the dry film transfer method, which includes a main layer. The layer contains a plurality of scattered particles, and the main layer has a right //, π-upper surface and a lower surface ', and adjacent to the upper surface and the lower surface, respectively, there is a separable upper protective film and Protect the film.
