At present, OCs on color filters are mainly manufactured by spin coating. In this method, a protective film material in the form of a solution containing an organic solvent is applied to the center of a substrate on a color filter, and the substrate is rotated at a predetermined rotation speed for a predetermined time to form a uniform film thickness on the color filter. Is applied in the form of a solution. Further, the solution-like protective film material is put together with the color filter substrate in an oven or on a hot plate, and the organic solvent contained in the solution-like protective film material is sufficiently dried. Cured using both heat to form OC with uniform thickness. There are also a roll coating method and a dipping method, but the protective film is formed in the same process except that the method of applying the protective film material to the substrate is different from the spin coating method. The roll coating method is a method in which a roller is wetted in advance with a solution-like protective film material, and the solution-like protective film material is brought into contact with a color filter and applied while rotating the roller. The dip method is
This is a method in which a color filter is put into a protective film material in the form of a solution, and the color filter is pulled up and applied. In both the roll coating method and the dipping method, the steps after the drying of the organic solvent are the same as in the spin coating method.

However, these methods involve the steps of applying a solution-like protective film material on a glass substrate, drying and curing the contained solvent to form a film, and thus the process is performed until the solvent evaporates. Defects frequently occur due to adhesion of foreign matter in the wet process. On the other hand, in the recently proposed film transfer method, the mixing of foreign substances is drastically reduced because OC can be formed by a dry process. However, when a conventional transfer film without a thermoplastic resin layer is used, a color filter pixel is formed. Since there is unevenness in the shape of
Or unevenness in optical characteristics due to poor followability to the pixel shape. The present invention provides a method for eliminating the occurrence of defects and optical unevenness due to the attachment of foreign matter to an optical element.

Polystyrene, polycarbonate, and polyimides. Among them, particularly preferred is biaxially oriented polyethylene terephthalate having excellent dimensional stability and permeability. The thickness of the base film is preferably from 6 to 100 μm. When the thickness is 6 μm or less, the surface roughness of the laminating roll or the like is transferred to the underlying thermoplastic resin layer and the light-transmitting protective film layer during lamination, and the surface of the light-transmitting protective film layer may be roughened. The thermoplastic resin layer can be formed into a sheet, has no tackiness at normal temperature, and has a smoothness of 0.0
Those having a size of 5 μm or less are desirable. The hardness at the temperature at which the transfer film is laminated on the transparent substrate (JIS K630)
It is more preferable that 1) is 80 degrees or less. The reason for this is
If the hardness is too high, pressure will not penetrate into the edge of the uneven pattern formed on the transparent substrate, bubbles will enter, and the thickness of the protective film layer transferred to the edge will increase, and the flatness of the formed uneven pattern will be improved. It is to spoil. The thickness of this layer is desirably greater than the thickness of the protective film layer, and at least twice as thick.
