Problems solved by technology

[0004] If a dye is used as a coloring compound, it is useful in terms of improving the color tone or brightness of the displayed image during image display by utilizing the color purity of the dye itself or the vividness of the color tone, but the current situation is that the color filter using the dye There is still room for improvement in the image characteristics of light sheets, and further improvements are required in contrast and brightness performance

Abstract

Provided is a colored curable composition with which brightness is increased while obtaining high contrast and which is useful in colored pattern formation for a color filter. Also provided are a color filter and a display device. The colored curable composition comprises: one or more dye compounds selected from (A-1) a dipyrromethene metal complex compound wherein the structure represented by general formula (I) is coordinated to a metal or metal compound and (A-2) azapyrromethene metal complex compounds wherein the structure represented by general formula (II) is coordinated to a metal or metal compound; and (B) a porphyrin compound represented by general formula (III). R1-R6 and R21-R26 are hydrogen atoms or monovalent substitution groups. R7 is a hydrogen atom, halogen atom, alkyl group or the like. In general formula (III), Z1-Z4 are N or C-R, A1-A8 are hydrogen atoms, alkyl groups or the like, and at least one pair from the pairs A1 and A2, A3 and A4, A5 and A6, and A7 and A8 does not have a cyclic structure. M is a divalent metal ion or the like.

Description

technical field [0001] The present invention relates to a coloring curable composition containing a dye as a coloring compound, a color filter, a method for producing the color filter, and a display device. Background technique [0002] As one of methods for producing color filters used in liquid crystal display devices, solid-state imaging devices, and the like, a pigment dispersion method is widely used. As the pigment dispersion method, there is a method of producing a color filter by photolithography using a colored curable composition in which a pigment is dispersed in various photosensitive compositions. Since this method contains a pigment, it is stable to light or heat, and patterning is carried out by photolithography, so the position accuracy is sufficiently ensured, and it is suitable for use in liquid crystal display devices, electroluminescent (electroluminescent, EL) display devices, etc. A method of manufacturing color filters for color displays. [0003] As...
