Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter, and more particularly, to a color filter having excellent spectral absorption characteristics and having little blur of a pixel pattern.

[0002]

2. Description of the Related Art A color filter is used for a display panel using liquid crystal, a CCD solid-state image pickup device, a color face plate for CRT display, a photoelectric conversion element plate for copying, a filter for a single tube type color television camera, and the like. The color filter is formed by regularly arranging the three primary colors of red, green and blue, but there is also a color filter having four or more hues as necessary.

As a method for producing a color filter, for example, a process of dyeing a dye on a patterned relief formed on a photosensitive portion of dichromated gelatin is repeated three times to obtain blue (B), green (G), A method of creating a color filter having a pattern of three colors of red (R) is known.

[0004] Typical color filter production methods including the above methods include the pigment dispersion method, vapor deposition method, dyeing method, printing method, electrodeposition method, resist electrodeposition transfer method, and the like.
In addition, as a method whose manufacturing process is relatively simple, there is a manufacturing method using a silver halide photosensitive material. When the color filter thus obtained is used in a liquid crystal display or the like, it will be subjected to a process of being exposed to high temperatures, so it is of course necessary to improve the spectral absorption characteristics. It is also necessary to impart the property. In addition, a glass substrate is often used as a support substrate, but various proposals have been made for a color filter using a light-transmitting plastic film substrate in order to improve handling properties. However, it is difficult to impart the above-mentioned spectral absorption characteristics and heat resistance, and the present inventors have studied an improvement method thereof.

Therefore, the present inventor tried to use a substrate having a high glass transition point as a plastic film substrate, but this alone did not provide sufficient heat resistance, and in particular, bleeding appeared at a boundary portion of a pixel pattern of a color filter. A new challenge was found.

On the other hand, JP-A-3-212602 proposes a method for adjusting the amount of a high-boiling organic solvent. Although this method was effective for spectral absorption characteristics and heat resistance, it was not yet sufficient. In order to further enhance the effect, the present inventors have conducted various studies, and as a result, in a color filter using such a high-boiling organic solvent, when the amount of the high-boiling organic solvent added is large, the spectral absorption characteristics are further improved. I found something. However, a color filter using a high-boiling organic solvent has a new problem that, after high-temperature treatment, bleeding occurs at the boundary of the pixel pattern of the color filter, and this bleeding is particularly large when the amount of the high-boiling organic solvent is large. I understood that.

Further, when a liquid crystal display device is manufactured using a color filter on a plastic film substrate, a new problem has been found that the manufacturing yield is poor.

Therefore, the inventor conducted various studies, and as a result,
It has been found that the method of the present invention makes it possible to produce a good color filter that has excellent spectral absorption characteristics and has little bleeding at the pixel pattern boundary even after high-temperature processing, and manufactures a liquid crystal display device using a color filter on a plastic film substrate. The inventors have found that the yield can be improved, and have reached the present invention.

Conventionally, the color development time is generally about 3 minutes and 30 seconds, but in the present invention, it is preferably within 40 seconds, and more preferably within 25 seconds.

To the color developing solution, known developing component compounds can be added in addition to the above color developing agents. Usually, alkaline agents having a pH buffering action, chloride ions, development inhibitors such as benzotriazoles, preservatives,
A chelating agent or the like is used.

The silver halide photographic light-sensitive material of the present invention is subjected to bleaching and fixing after color development. The bleaching process may be performed simultaneously with the fixing process. After the fixing process,
Usually, a water washing process is performed. Further, as an alternative to the water washing treatment, a stabilization treatment may be performed. The developing apparatus used for the development of the silver halide photographic light-sensitive material of the present invention may be a roller transport type in which the light-sensitive material is conveyed between rollers disposed in a processing tank, and the belt may be provided with the light-sensitive material. The processing tank may be formed in a slit shape, and the processing liquid may be supplied to the processing tank and the photosensitive material may be transported, or the processing liquid may be sprayed. Spray method,
A web method by contact with a carrier impregnated with the processing solution,
A method using a viscous treatment liquid can also be used. When processing in large quantities, it is normal to run using an automatic developing machine, but in this case, the replenishment amount of the replenisher is preferably as small as possible. The most preferred method is to add a treating agent in the form of the method described in JP-A-94-16935.

In the color filter manufactured by the method of the present invention, a resin having heat resistance, water resistance and high specific electrical resistivity can be applied as an overcoat layer to the outermost layer. Examples of such resins are described in U.S. Pat. No. 4,698,295.

No. 36A, JP-A-3-163416 and the like. The color filter produced by the method of the present invention can be further provided with a transparent electrode (ITO) by vapor deposition coating, for example, by vacuum vapor deposition or sputtering.
Furthermore, an alignment film such as a polyimide resin can be provided thereon. A polarizing plate or a retardation film may be provided on the surface of the color filter opposite to the emulsion surface of the light transmitting substrate.

An example of a color liquid crystal display device using the color filter of the present invention will be described.

FIG. 1 is a plan view showing an example of a color developing state of the color filter of the present invention. A black black matrix is formed between each pixel of B (blue), G (green), and R (red).

FIG. 2 is a sectional view showing an example of a color liquid crystal display device using a color filter.

Although not shown in the drawings, the surface of the color filter 2 of the present invention is covered with the above-mentioned resin for overcoating to form a protective layer. The transparent electrode 3 is attached on the color filter using a vacuum film forming apparatus. The transparent electrode 3 is generally formed as an integral electrode in an active matrix drive LCD using a three-terminal switching array such as a TFT, and is usually formed as a stripe electrode in a simple matrix drive LCD such as an STN.
Under the transparent electrode 3, an alignment layer 4 of polyimide or the like for aligning the liquid crystal 5 is arranged. Further, a transparent electrode and an alignment layer are arranged on the glass substrate 7 opposite to the liquid crystal layer. A black matrix 9 is usually formed between the R, G, and B pixels to control on / off of a liquid crystal shutter and to improve contrast and color purity. The black matrix 9 can be formed simultaneously with each of the R, G, and B pixels as in the present invention, or a Cr film, a carbon film, or the like can be separately formed. Polarizing plates 10 and 11 are provided on the back surfaces of the glass substrates 1 and 7. A phase compensation film can be provided between the glass substrate and the polarizing plate.

Since the light transmittance of an LCD using a normal color filter is small, a backlight 12 is provided as a light source having compatibility with the normal color filter. However, the backlight 12 can be used as a color filter for a reflective LCD. As the light transmitting substrate, the plastic film substrate of the present invention can be used.
