    Abstract: PROBLEM TO BE SOLVED: To obtain a light emitting element which has high luminosity, high color purity, and high efficiency of an electric energy. SOLUTION: A light emission element in which a luminescence substance exists between a positive electrode and a negative electrode, and emits light by the electric energy, is characterized by inclusion of a compound shown in formula (1) at least. In the formula (1), A is a perinone derivative and B is a substitution group of which the isotoropic rotation to A is restricted by a solid repulsion between A-B or between B-B. The n is one of natural numbers of 1-4.

SOLUTION: A light emitting element in which a luminescence substance exists between a positive electrode and a negative electrode, and emits light by the electric energy, is characterized by inclusion of a compound shown in formula (1) at least. In the formula (1), A is a naphthalimido derivative and B is a substitution group of which the isotoropic rotation to A is restricted by a solid repulsion between A-B or between B-B. The n is one of natural numbers of 1-4.

    Abstract: PROBLEM TO BE SOLVED: To provide a light emitting element low in drive voltage and excellent in durability, and a material for the light emitting element constituting the element. SOLUTION: The material for a light emitting element includes a compound expressed by general formula (1), and the element using the material as a light-emitting substance existing between an anode and a cathode emits light by an electric energy. In formula (1), A is a substituent having a phenanthroline skeleton or a benzoquinoline skeleton, B is an organic group of n-valent having a structure expressed by general formula (2), and n is a natural number equals to 2 or more. In formula (2), R 1 and R 2 are either of an alkyl group or an aryl group independent on each other (including an aryl group condensed to a phenyl group), l and m are independently natural numbers of 0 to 5 respectively, and X is at least one kind selected from structural formula (3).

    Abstract: PROBLEM TO BE SOLVED: To obtain both a fine pigment dispersion and a colorant composition having excellent flow characteristics and dispersion stability and to thereby provide a color filter having excellent surface roughness and contrast of a pixel film. SOLUTION: This pigment dispersion is characterized as comprising a pigment dispersing agent represented by the general formula (1): P-(NHCO-X-Y)n [wherein, P denotes a pigment residue; X denotes an aryl group; n denotes an integer of 1-4; and Y is selected from carboxy group, ester group, hydroxy group, mercapto group, amino group, sulfo group and groups represented by the general formula (2); (CH2)m-NR1R2 (wherein, R1 and R2 may be each the same or different and are each selected from hydrogen, an alkyl group and an aryl group; and m denotes an integer of 1-6). The colorant composition is characterized as comprising the pigment dispersing agent in the colorant composition consisting essentially of a pigment, a resin and a solvent. The color filter is characterized in that colored layers are colored films formed from each colorant composition in the color filter having pixels comprising the colored layers provided in an optional number of colors in a desired pattern form for each color.
