Blue color composition containing dye, color filter and liquid crystal display device and organic EL display provided with the color filter

An embodiment of the present invention will be disclosed below. A bank substrate comprising: a substrate and a bank on the substrate, wherein a surface energy of the bank is 30 to 45 mJ/m. Further, colored pixels are present between zones of the bank, and the difference of height within a pixel of the colored pixels is 0.3 &#x3bc;m or less. The colored pixels comprise colored inks, and a viscosity of the colored inks is 50 mPa&#xb7;s or less.

Substrate provided with bank and substrate provided with color pattern

A colored alkali-developable photosensitive resin composition comprising an alkali-developable resin composition that contains a reaction product obtained by esterification of an epoxy-adduct with a polybasic acid anhydride (C) and then with a polyfunctional epoxy compound (D), wherein the epoxy-adduct has a structure in which an unsaturated monobasic acid (B) is added to an epoxy resin (A) represented by general formula (I) below, a coloring material (E) and a photopolymerization initiator (F). wherein Cy represents a cycloalkyl group having 3 to 10 carbon atoms; X represents a hydrogen atom, a phenyl group, or a cycloalkyl group having 3 to 10 carbon atoms; the phenyl group or the cycloalkyl group having 3 to 10 carbon atoms is optionally substituted with an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, or a halogen atom; each of Y and Z independently represents an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, or a halogen atom, wherein the alkyl group, the alkoxy group, and the alkenyl group are optionally substituted with a halogen atom; n represents a number of 0 to 10; p represents a number of 0 to 4; and r represents a number of 0 to 4.

Colored alkali-developable photosensitive resin composition and color filter using the same

An alkali-developable, colored photosensitive resin composition obtained by adding a colorant and a photopolymerization initiator to an alkali-developable resin composition, containing a reaction product obtained by esterification between an epoxy adduct and a polybasic acid anhydride, the epoxy adduct having a structure formed by adding an unsaturated monobasic acid and a compound selected from a phenol compound, an alcohol compound, an amine compound, and a carboxylic acid to an epoxy resin represented by general formula. The epoxy adduct is formed by adding 0.1 to 1.0 carboxyl group of the unsaturated monobasic acid and 0 to 0.9 phenolic hydroxyl group, alcoholic hydroxyl group, amino group or carboxyl group per epoxy group of the epoxy resin, with the sum of the carboxyl unsaturated monobasic acid and the phenolic hydroxyl group, alcoholic hydroxyl, amino or carboxyl group being 0.1 to 1.0 per epoxy group.
