In recent years, in all spectras such as liquid crystal TV set, LCD monitor, color liquid crystal mobile phone, bring into use color liquid crystal display arrangement.One of important parts that color filter is the identification of control color liquid crystal display arrangement, in order to obtain the raising of identification, i.e. distincter image, the black matrix of color filter must be realized further high shading, must be in photosensitive polymer combination the light screening materials such as pigment that add in large quantities compared with the past.
Yet, produce following problem: if increase the content of the light screening materials such as pigment, when color filter forms, in black photoresistance film, the light of ultraviolet range becomes and is difficult to arrive the deep of filming, and the pattern while producing the closely sealed bad of pattern or development because of curing bad in Photocurable composition peels off, the sharp keen property reduction of edge shape.
Therefore, even in the situation that the light screening materials such as pigment that contain high concentration do not produce yet solidify bad, use the acrylic monomers that highly sensitive Photoepolymerizationinitiater initiater or the degree of polymerization are high, but in current technology, about Photoepolymerizationinitiater initiater or acrylic monomers, present situation is that high-sensitivity reaches capacity, in the high concentration field of the light screening materials such as pigment, existence can not obtain for carry out sufficient sensitivity that good pattern forms or with the problem of the adaptation of glass substrate and the storage stability of photosensitive polymer combination.
Therefore, proposed before the inventor etc. as the alkali soluble resin using when the Pigments, utilize the acid adduct of specific epoxy (methyl) acrylate, use and have the photosensitive polymer combination for color filter (with reference to patent documentation 1) that they is divided into together with spreading agent to loose pigment dispersion.According to described photosensitive polymer combination, in the field of the light screening materials such as pigment that contain the high concentration that realizes high shading with black matrix, there is high sensitivity, the high adhesion energy to glass substrate, and can realize the storage stability of photosensitive polymer combination excellence.
But, in order to become brighter, distincter color filter, in the mode that the further graph thinning of black matrix, obscurity are also improved, require more and more High Level of characteristic, and, due to the display mode of liquid crystal, must make black matrix than in the past higher resistance.Become when realizing the addition of the light screening materials such as high-caliber so high shading, high-resistance pigment, cannot guarantee fully the development adaptation of the thread pattern below 10 μ m, while assembling color filter on liquid crystal panel, be also difficult to compared with highland, maintain the problem with the adaptation of glass substrate by sealant.
