Benefits of technology

[0010] In order to solve the above-mentioned problems, an object of the present invention is to provide a method for forming an image easily, which is used suitably by a reflection and transmission LCD wherein the film thickness of a colored layer is partially varied in each pixel; and a method for easily forming a spacer and a projection for orientation control.

Problems solved by technology

However, a problem of a reduction in display quality in rooms and dark places has been noticed.
In the case that sufficient brightness is realized for reflection display, the color purity of the transmission portion is insufficient.
In the case that the color purity of the transmission portion is conversely made sufficient, an inconvenience, wherein the reflection portion becomes dark, is caused.
However, this process is complicated and the costs rise.
Thus, costs of the LCD panel rise.

(Formation of a Color Filter)

[0075] Prepared was a polyethylene terephthalate film pre-support (75 μm in thickness) undercoated with a gelatin layer (0.2 μm in thickness). A coating solution having the following formulation H1 was applied onto the gelatin layer surface and dried to form a thermoplastic resin layer (20 μm in dry film thickness).

[0076] Thermoplastic Resin Layer Formulation H1:

Methyl methacrylate / 2-ethylhexyl acrylate / 15parts by massbenzyl methacrylate / methacrylic acid copolymer(copolymer composition ratio (mole ratio) =55 / 4.5 / 11.7 / 28.8) (weight-average molecularweight = 90000)Polypropylene glycol diacrylate (average6.5parts by massmolecular weight = 822)Tetraethylene glycol dimethacrylate1.5parts by massp-Toluenesulfonamide0.5part by massBenzophenone1.0part by massMethyl ethyl ketone30parts by mass.

(Formation of a Color Filter)

[0089] A color filter of Example 2 was formed in the same way as in Example 1 except that instead of the formation of the three colored photosensitive resin layers of red (R1), green (G1) and blue (B1) in Example 1, three photosensitive solutions of red (R1), blue (B1) and green (G1) each having a formulation shown in Table 1 were directly applied onto a polyethylene terephthalate film pre-support (75 μm in thickness), and dried to form three colored photosensitive resin layers (1.2 μm in film thickness).

Abstract

An image forming method of the invention is an image forming method comprising the steps of exposing, through a photo mask, a substrate, on which a first negative photosensitive resin layer and second negative photosensitive resin layer are formed, wherein the photo mask is a photo mask having at least two light transmittable patterns, and the photosensitivity ratio of the first negative photosensitive resin layer to the second negative photosensitive resin layer is more than 1. This method makes it possible to form an image easily, which is used suitably by a reflection and transmission LCD display wherein the film thickness of a colored layer is partially varied in each pixel, and to easily form a spacer and a projection for orientation control.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an image forming method; and a color filter, a spacer for liquid crystal display, and a projection for orientation control, which are formed by the image forming method. More specifically, the invention is an image forming method used suitably by liquid crystal display devices for reflection and transmission displays; and a color filter, a spacer for liquid crystal displays, and a projection for orientation control, which are formed by the image forming method. [0003] 2. Description of the Related Art [0004] A color filter is used in a color face plate for cathode ray tube displays, a photoelectric conversion element plate for copying, a filter for single-tube system color television cameras, a flat panel display using liquid crystal, a color solid state image pickup device, or the like. A conventionally used color filter is made by regularly arranging the three primary colors (blue,...
