であった。However, the conventional dyeing type hologram manufacturing method shown in FIG. 2 requires a complicated manufacturing process, which increases the manufacturing cost and makes it difficult to manufacture a hologram having a sufficient resolution. Further, since three pattern exposures for three colors of cyan, magenta and yellow are required, it is extremely difficult to align the positions.
本発明は上記問題点を解決するためのもので、ホトリ

作製方法を提供することを目的とする。The present invention has been made to solve the above problems, and it is an object of the present invention to provide a method of manufacturing a color filter which can eliminate a photolithography step, precise alignment, and the like, and can obtain a sufficient resolution. Aim.

複製することを特徴とする。Therefore, the present invention, R, G, master hologram composed of a Lippmann hologram in which a pattern of a color filter composed of B information is recorded, the photosensitive material is disposed facing,
It is characterized by irradiating mixed light of three colors of R, G and B from the photosensitive material side and transferring and copying the color filter pattern of the master hologram to the photosensitive material.

できるので、フォトリソの工程、精密な位置合わせ等を
不要とすることができる。The present invention provides a Ripman hologram in which R, G, and B color filters are recorded, as a master hologram, facing a photosensitive material, and irradiating mixed light of three colors from the photosensitive material side, so that R, G, Since the reproduced image of the B color filter is transferred and duplicated on a photosensitive material to produce a color filter, a photolithography process, precise alignment, and the like can be eliminated.
以下、実施例を図面を参照して説明する。 Hereinafter, embodiments will be described with reference to the drawings.
第１図は本発明のカラーフィルタの作製方法を説明す
るための図である。図中１は感光材料、２はマスターホ
ログラムである。FIG. 1 is a diagram for explaining a method for producing a color filter of the present invention. In the figure, 1 is a photosensitive material, and 2 is a master hologram.
図において、マスターホログラム２はリップマンホロ
グラムであり、それぞれの領域はR,G,Bの干渉パターン

光材料１に記録される。こうして一度の露光でマスター
ホログラム２のパターンが感光材料１に転写複製される
ことになる。In the figure, a master hologram 2 is a Lippmann hologram, and an R, G, B interference pattern is recorded in each area. The photosensitive material 1 is arranged to face the master hologram 2. And from the photosensitive material 1 side
When the mixed light of R, G, and B is irradiated, interference occurs between the reflected light from the master hologram 2 and the incident light, and the interference fringes are recorded on the photosensitive material 1. Thus, the pattern of the master hologram 2 is transferred and copied to the photosensitive material 1 by one exposure.
なおこの場合、感光材料とマスターホログラムの間隔
が大き過ぎると、隣接領域からの反射光が混入し、その
干渉縞も同一場所に記録されるて像のボケが生じてしま
う。したがって、両者の間隔はなるべく狭くする必要が
あり、パターンの大きさ程度、例えばストライプ型フィ
ルタの場合ではストライプの間隔の２分の１以下程度と
することが好ましい。In this case, if the distance between the photosensitive material and the master hologram is too large, reflected light from an adjacent region is mixed in, and the interference fringes are also recorded in the same place, resulting in image blur. Therefore, it is necessary that the distance between the two be as small as possible, and it is preferable that the distance between the two be as small as about the size of the pattern, for example, about half the distance between the stripes in the case of a stripe type filter.
また、上記実施例ではストライプフィルタについて説
明したが、本発明は必ずしもこれに限定されるものでな
く、例えばメッシュ状フィルタ等に適用してもよいこと
を言うまでもない。Further, in the above-described embodiment, the stripe filter has been described. However, the present invention is not necessarily limited to this, and it is needless to say that the present invention may be applied to a mesh filter or the like.
以上のように本発明によれば、１回の露光でR,G,Bカ
ラーフィルタの再生像を感光材料に転写複製することに
より、精密な位置合わせを要することなく、解像度のよ
いカラーフィルタを作製することができる。As described above, according to the present invention, a reproduced image of an R, G, B color filter is transferred and duplicated on a photosensitive material in a single exposure, so that a color filter having good resolution can be obtained without requiring precise alignment. Can be made.
