Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はホログラフィ技術を応用したカラーフィルタの
作製方法に関する。The present invention relates to a method for manufacturing a color filter to which a holographic technique is applied.
従来、各種分野で利用されているカラーフィルタとして
染色タイプのものが用いられてきたが、その製造工程が
複雑なため、それに代えてホログラフィ技術を応用して
カラーフィルタを作製することが試みられている。Conventionally, a dyeing type has been used as a color filter used in various fields, but since the manufacturing process is complicated, it is attempted to produce a color filter by applying a holographic technique instead. There is.
第３図はこのような従来のホログラフィ技術を応用した
カラーフィルタ作製方法を説明するための図である。FIG. 3 is a diagram for explaining a color filter manufacturing method to which such a conventional holographic technique is applied.

タを作製している。In the figure, the photosensitive material 12 and the mirror 13 are arranged to face each other, and further, for example, a mask 11 having a stripe pattern is arranged in close contact with the photosensitive material 12, light is incident from the mask 11 side, and reflected light from the mirror 13 The interference fringes are recorded on the photosensitive material 12 to record a stripe-shaped mask image to produce a color filter.
しかしながら、第３図に示すような従来の作製方法で
は、感光材料とマスクを密着させる場合にゴミ等がはさ
まっていると、ギャップが変化してボケが生じ、感光材
料とマスクとを常に一定の関係で密着させることは非常
に困難であった。However, in the conventional manufacturing method as shown in FIG. 3, when the photosensitive material and the mask are brought into close contact with each other and dust or the like is trapped, the gap changes to cause blurring, and the photosensitive material and the mask are always kept constant. Due to the relationship, it was very difficult to bring them into close contact.
また、一定の間隔での密着が行えたとしてもマスクのイ
メージは感光材料自体の厚みに起因するボケを生ずる。Further, even if the contact is made at a constant interval, the image of the mask is blurred due to the thickness of the photosensitive material itself.
本発明は上記問題点を解決するためのもので、マスクと
感光材料との精密な密着を要せず、シャープなマスク像

る。To this end, the present invention provides a photosensitive material and a mask having a predetermined pattern which are spaced apart from each other by a predetermined distance to face each other, and irradiates the photosensitive material and the mask with light from opposite directions to produce a hologram, and then the hologram and the photosensitive material. Are separated from each other by a predetermined distance and face each other, and reproducing light is irradiated from the side of the photosensitive material to reproduce and record the mask image in the photosensitive material.

こときができるので、像のボケが生ずることがなく、精
細なカラーフィルタを作製することが可能となる。According to the present invention, a photosensitive material and a mask are isolated from each other for a certain period of time, and light is irradiated from the opposite sides, a mask image and a reference light are interfered with each other to form a hologram, and then a reproduced image of the hologram is reproduced in the photosensitive material. In this way, the filter is produced in such a manner that it is possible to reproduce the mask image in the photosensitive material layer without the need for precise contact between the mask and the photosensitive material. It is possible to produce a fine color filter without any occurrence.
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、第２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、図中、１は感光材料、２はマス
ク、3,4は照射光、５は感光材料、６は再生光である。FIGS. 1 and 2 are views for explaining a method for producing a color filter of the present invention, in which 1 is a photosensitive material, 2 is a mask, 3 and 4 are irradiation light, 5 is a photosensitive material, and 6 is It is a reproduction light.
まず、第１図に示すように、感光材料１とマスク２とを
所定間隔Ｄだけ離して配置する。マスク２には、例えば

光材料１に干渉縞を記録してリップマンホログラムを作
製する。First, as shown in FIG. 1, the photosensitive material 1 and the mask 2 are arranged apart from each other by a predetermined distance D. For example, a stripe pattern is drawn on the mask 2. Then, irradiate with light 3 and 4 from opposite sides of the photosensitive material 1 and the mask 2, respectively.
An interference fringe is recorded on the photosensitive material 1 using the light transmitted through the mask 2 as object light and the light 3 as reference light to produce a Lippmann hologram.

きる。したがって感光材料とマスクとは精密な密着を要
することはない。Next, as shown in FIG. 2, the hologram 1 and the photosensitive material 5 thus produced are separated from each other by a predetermined distance, and the reproduction light 6 is irradiated from the photosensitive material 5 side. As a result, distance D from hologram 1
The mask image is reproduced at a position separated by. Therefore, the photosensitive material 5 is positioned so that the photosensitive material 5 and the reproduced image overlap each other. Since the reproduced image and the light-sensitive material layer can be superposed in this way, an extremely sharp image can be recorded without blurring, and a fine color filter can be manufactured. Therefore, there is no need for precise contact between the photosensitive material and the mask.
なお、照射光３、４として、それぞれR,G,B光を使用

カラーフィルタを作製する事が可能である。It should be noted that R, G, and B lights are used as the irradiation lights 3 and 4, respectively, and R, G, and B stripe images can be recorded on one photosensitive material if the mask position is shifted and the light is exposed three times. , R, G, B by using R, G, B light as reproduction light 6
It is possible to reproduce and record a stripe image to produce a color filter. Further, the R, G, B stripe images are recorded on each of the three photosensitive materials, and the hologram and the photosensitive material are recorded at different positions during reproduction, so that a color filter can be similarly produced.
