  The color filter is an indispensable component for a liquid crystal display (hereinafter also referred to as “liquid crystal display device”). This liquid crystal display is very compact and is equivalent to or better than conventional CRT displays in terms of performance, so it is replacing the CRT display.

  In the formation of a color image on a liquid crystal display, the light passing through the color filter is directly colored into the colors of the respective pixels constituting the color filter, and the light of those colors is synthesized to form a color image. At present, a color image is formed by pixels of three colors of RGB.

In recent years, the development of technology for increasing the screen size and the definition of liquid crystal displays has progressed, and its applications have been expanded from displays for notebook computers to monitors for desktop computers and further to television monitors. Under such circumstances, high color purity is also required for color filters used in liquid crystal displays.
In addition, for products that require popularity, such as LCD color televisions and liquid crystal displays for computers, cost reduction is the most important issue as well as quality, and a method for manufacturing color filters that can reduce manufacturing costs is desired. Has been.

  However, the color filters for large screens that have been used in the past have not yet obtained sufficient color purity, and further improvement in manufacturing cost has been desired (for example, see Patent Document 1). In particular, in the conventional color filter, it is necessary to increase the amount of light of the backlight. However, if a backlight having a large amount of light is used, the cost increases.

In addition, a color filter having a spacer portion in which two colors having different spectral characteristics are partially overlapped has been proposed (see, for example, Patent Document 2). ). This color filter can form a uniform liquid crystal layer, and is excellent in display quality of luminance unevenness and color unevenness. However, if the height of the overlapped portion is not uniform or the hardness is insufficient, the role as a spacer cannot be sufficiently achieved.

Although not particularly limited, the thickness of the oxygen blocking film is generally preferably 0.5 to 3.0 μm.

-Exposure process and development process-
In the exposure step, a predetermined mask is arranged above the photosensitive resin layer formed on the substrate, and then from above the mask through the mask, the thermoplastic resin layer, and an intermediate layer provided as necessary. The color filter of the present invention can be obtained by repeating the steps of exposing and then developing with a developing solution in the developing step by the number of colors.
Here, the light source for the exposure can be appropriately selected and used as long as it can irradiate light in a wavelength region capable of curing the photosensitive resin layer (for example, 365 nm, 405 nm, etc.). Specifically, an ultrahigh pressure mercury lamp, a high pressure mercury lamp, a metal halide lamp, etc. are mentioned. As an exposure amount, it is about 5-200 mJ / cm < ² > normally, Preferably it is about 10-100 mJ / cm < ² >.

The developer is preferably one in which the photosensitive resin layer exhibits a dissolution type development behavior. For example, a developer containing a compound having a pKa of 7 to 13 at a concentration of 0.05 to 5 mol / L is preferable. A small amount of a miscible organic solvent may be added.
Examples of organic solvents miscible with water include methanol, ethanol, 2-propanol, 1-propanol, butanol, diacetone alcohol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol mono-n-butyl ether, and benzyl alcohol. , Acetone, methyl ethyl ketone, cyclohexanone, ε-caprolactone, γ-butyrolactone, dimethylformamide, dimethylacetamide, hexamethylphosphoramide, ethyl lactate, methyl lactate, ε-caprolactam, N-methylpyrrolidone and the like.

In particular, in the shower development, an uncured portion can be removed by spraying a developer onto the exposed photosensitive resin layer by shower. Prior to development, it is preferable to spray an alkaline solution having a low solubility of the photosensitive resin layer with a shower or the like to remove the thermoplastic resin layer, the intermediate layer, and the like. Further, after development, it is preferable to remove the development residue while spraying a cleaning agent or the like with a shower and rubbing with a brush or the like.
The liquid temperature of the developer is preferably 20 ° C. to 40 ° C., and the pH of the developer is preferably 8 to 13.

  In the production of the color filter of the present invention, as described in JP-A No. 11-248921 and Japanese Patent No. 3255107, a colored photosensitive resin composition for forming a color filter is layered to form a base, It is preferable from the viewpoint of cost reduction that a transparent electrode is formed thereon and a spacer is formed by further overlapping the divisional alignment protrusions. In the present invention, it is particularly preferable to form a spacer by applying or transferring the green photosensitive resin composition after applying or transferring the red photosensitive resin composition onto the substrate.

  In the present invention, the green photosensitive resin composition is applied or transferred to at least a part of the red resin layer formed by applying or transferring the red photosensitive resin composition on the substrate. It is preferable to form a spacer by laminating a green resin layer. By using this laminated portion as a spacer, a color filter can be easily produced with a small number of conventional processes.

In the case where the colored photosensitive resin composition is sequentially applied and laminated, the film thickness decreases as the layers are overlapped due to the leveling of the coating solution. For this reason, it is preferable to overlap the four colors of K (black), R, G, and B, and further overlap the divisional alignment protrusions. On the other hand, in the case of using a transfer material having a thermoplastic resin layer, it is preferable that three or two colors be superimposed because the thickness is kept constant.
Further, the size of the base (the size of the above-mentioned photosensitive resin layer laminated portion) is preferably 25 μm or more from the viewpoint of preventing the deformation of the photosensitive resin layer when the transfer material is laminated and maintaining a constant thickness. 30 μm or more is particularly preferable.

-Bake process-
In the present invention, a baking step is performed in order to make a hard film by reacting a polymerizable compound such as a monomer or an oligomer. Baking while providing each color is preferably performed at 200 to 240 ° C. for about 10 to 20 minutes. Moreover, after forming all the colors, it is preferable to perform a baking process at 200 to 240 ° C. for about 30 to 180 minutes. The temperature and time during baking are preferably set to a higher temperature and a shorter time so that yellowing due to baking is prevented and production tact is not lost.
By passing through the above process, the color filter of this invention can be produced.

<Liquid crystal display device>
The liquid crystal display device of the present invention is not particularly limited as long as it uses the color filter of the present invention having a good chromaticity in an F10 light source field of view of 2 degrees. ECB (Electrically Controlled Birefringence), TN (Twisted Nematic) ), IPS (In-Plane Switching), FLC (Ferroelectric Liquid Crystal), OCB (Optically Compensatory Bend), STN (Supper Twisted Nematic), VA (Vertically Aligned), HAN (Hybrid Aligned Nematic), GH (Guest Host) Various display modes can be adopted. The liquid crystal display device of the present invention is characterized by using a color filter using the above-described composition set of the present invention, thereby realizing high color purity and effective coating unevenness (color unevenness due to film thickness variation). Therefore, it can be suitably used for a large-screen liquid crystal display device such as a notebook personal computer display or a television monitor.
In addition, since the color filter of the present invention has a high transmittance, a backlight with a low light quantity can be used, and the cost can be reduced.

  As described above, when a color filter is produced using the composition set of the present invention, it is possible to process the spacer simultaneously with the formation of the colored pixels, and the conventional spacer production process can be omitted, and the production cost can be reduced. Can be reduced. In addition, when the composition set of the present invention is used, the color tone can be made thinner than that of a conventional color filter, so that the luminance of the backlight can be lowered. From this point of view, the cost for manufacturing the liquid crystal display device can be reduced.
