Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a color filter. Recently, liquid crystal, plasma BL (electroluminescence),
Research is progressing on panels using LEDs (light emitting diodes), fluorescent display tubes, and the like. Among these, liquid crystal displays are being actively researched because they can be driven with low voltage and low power.

In order to display color on a liquid crystal display, a transparent substrate with an IJ rack-like structure and a transparent substrate with transparent electrodes provided on the entire surface are connected, with the transparent electrodes on the inside.
A liquid crystal is sealed in a cell that is bonded together via a spacer, sandwiched between a pair of polarizing plates, and a color filter is superimposed on this.

A color filter is one in which red, blue, and green images are provided on a transparent support in the form of a matrix.

The color filter may be used by being sandwiched between a transparent substrate provided with transparent electrodes and a polarizing plate. In addition, a transparent substrate with transparent electrodes provided on the entire surface is used as a transparent substrate for color filters, and a matrix-shaped image of red, blue, and green is provided on the surface of the transparent electrode or the opposite surface of the substrate, which can also be used as a color filter. .

[Conventional technology]

The conventional manufacturing method for color filters is as follows: (1) A color image is also printed on a transparent substrate with transparent electrodes arranged in a matrix.
A method of providing by IJ lax printing, (11) After forming a colored layer on a transparent substrate by coating, a photoresist is coated on it, image exposure is carried out in a matrix shape, and development is performed to form a resist mask in a matrix shape. There is a method in which, after formation, a step of selectively etching away the colored layer in the portions not covered with the resist mask is performed for the three colors red, blue, and green.

However, with method (1), an image with clear boundaries cannot be obtained due to bleeding of printing ink, and therefore,
It is difficult to obtain a color image with a finer pattern, and it is difficult to accurately align the three-color image patterns during printing, resulting in the disadvantage that the images partially overlap.

The method (II) requires many complicated manufacturing steps, resulting in high costs and has the disadvantage that it is difficult to accurately align images of each color. Furthermore, when a colored layer of a different hue is provided on a pattern of a colored image, a resist dyeing method is required so that the pattern of the colored image is not dyed, which has the disadvantage that the process becomes even more complicated.

[Problems to be solved by the present invention]

An object of the present invention is to provide a method for manufacturing a color filter having a finer colored image pattern, a method for manufacturing a color filter having a clear colored image pattern, and no bleeding at the boundaries of the image. To improve the accuracy of alignment of each color, to provide a method for producing a color filter that allows easy alignment of turns for images of each color, and to obtain a color filter at low cost through a simpler production process. A method for producing a color filter. It is about giving.

[Means for solving problems]

The object of the invention is achieved in the following way.

That is, the method involves placing a photosensitive resin layer containing one of red, blue, and green coloring materials on a substantially transparent support, and forming a colored image by exposure and development. After that, for the photosensitive resin layers containing the remaining two coloring materials, the photosensitive resin layers are placed on a transparent support, exposed to light, and developed, thereby creating a color filter. The method for manufacturing a color filter is characterized in that the photosensitive resin layer is installed by transferring the photosensitive resin layer provided on the temporary support to a transparent support. Alternatively, in a method for producing a color filter in which red, blue, and green images formed on seven temporary image receiving sheets are transferred onto a substantially transparent support, the red, blue, and green images are transferred to a substantially transparent support. After the formation of the photosensitive resin layer provided on the temporary support and containing a coloring material of one of three colors: dark red, blue, and green, onto the temporary image receiving sheet, exposure, and development, the above-mentioned Regarding the photosensitive resin layer containing each of the three remaining color materials,
This method of manufacturing a color filter is characterized in that it is performed by transferring to a temporary image-receiving sheet, exposing to light, and developing, respectively.

A - In addition to these three colors, other colors such as black stripes may be added.

A method of producing a colored image by exposing and developing a photoresist and transferring this to a final support to produce a color image is described in JP-A Shoj Tartuff/110.

Is this invention also covered by JP-A-Shoj? Materials described in Tarta lθ can be used.

There are no particular restrictions on the type of temporary support used to initially prepare the photosensitive resin layer, the temporary image receiving sheet, and the transparent support used as the color filter substrate, but significant deformation and shrinkage may occur under heating and/or pressure. Alternatively, it is necessary that no elongation occurs. Examples of such supports include polyethylene terephthalate films, cellulose triacetate films, polystyrene films, polycarbonate films, polymer-laminated paper glass plates, and the like.

Among these, transparent supports are preferable because alignment using transmitted light is easy. A biaxially oriented polyethylene terephthalate film or a glass plate is particularly preferred in terms of dimensional stability and transparency.

In this way, the sheet having the fcj color image was laminated with a polarizing film 6Varilite manufactured by Royal Electric Co., Ltd. and then laminated. By peeling off this temporary image receiving sheet and the polarizing film, red, A polarizing film with a color filter to which blue and green matrix images were transferred was obtained.

Example 3 A color filter was obtained by using a polyethylene terephthalate film having a thickness of about IOθμ in place of the polarizing film in Example 3.

Example Hiroshi - A color filter was produced by using a polycarbonate film provided with a transparent electrode instead of the polarizing film in Example 1 and transferring an image to the same side of the electrode.
