<P>PROBLEM TO BE SOLVED: To provide a color filter having high transmittance and excellent color purity, which achieves long life of an organic EL display including an organic EL light emitting body of trichromatic coating system having excellent color purity, and to provide a method for manufacturing the color filter. <P>SOLUTION: The color filter includes: a transparent base material 1; and a red coloring layer 3R, a green coloring layer 3G and a blue coloring layer 3B provided in a predetermined pattern on the transparent base material 1. Concerning the shape in a sectional view of an opening surface 12 of each coloring layer, the coloring layer having the opening surface 12A whose shape in a sectional view is symmetrical is one of the red coloring layer 3R and the green coloring layer 3G, and the coloring layer having the opening surface 12B whose shape in a sectional view is inclined in a fixed direction, in which the higher part in inclination is adjacent to the symmetrical coloring layer, is the other of the red coloring layer 3R and the green coloring layer 3G. The coloring layer whose shape in a sectional view is inclined in a fixed direction, which is inclined at a smaller angle than the angle of inclination of the inclined coloring layer, is the blue coloring layer 3B. <P>COPYRIGHT: (C)2011,JPO&INPIT |
