Claim:
1. A color filter for organic electroluminescence display device, which is used in an organic electroluminescence display device using, as a light emitting source, light from an organic EL layer of an organic electroluminescence element, wherein the color filter for organic electroluminescence display device comprises a transparent substrate, a colored layer that is a pixel region formed on the transparent substrate, a non-pixel area formed around the colored layer, a convex pillar formed in at least one spot of the non-pixel area and an auxiliary electrode layer formed on a top and a side of the convex pillar, and on the non-pixel area, wherein the auxiliary electrode layer has a metal auxiliary electrode layer and a transparent electrode layer, the metal auxiliary electrode layer is arranged into a linear pattern in the non-pixel area, the convex pillar is formed on the non-pixel area in which the metal auxiliary electrode layer is linearly arranged, and the transparent electrode layer is formed to cover the top and the side of the convex pillar, and the non-pixel area, and contact the metal auxiliary electrode layer, wherein a light shielding part is formed in the non-pixel area on the transparent substrate, an overcoat layer is formed to cover the light shielding part and the colored layer, the metal auxiliary electrode layer and the transparent electrode layer are formed on the overcoat layer, at least one singly-colored layer of the colored layers is laid on an entire surface of the light shielding part in the non-pixel area between the colored layers, the convex pillar is formed on the metal auxiliary electrode layer which is on the light shielding part where the colored layer is laid, and the transparent electrode layer formed on the top of the convex pillar is exposed outside so as to contact an upper-side transparent electrode layer in the organic electroluminescence element.
