Claim:
1. A color filter forming substrate for an organic EL display device, in which a pixel-dividing light-shielding region is arranged over one surface of a base material comprising a transparent substrate to make plural pixel regions into a region-divided form, and plural color-filter-forming coloring layers of multiple colors are arranged to a predetermined pixel region in accordance with a respective color, wherein the color filter forming substrate is a counter substrate facing an organic EL element forming substrate comprising an organic EL element, a light-shielding layer is arranged in the pixel-dividing light-shielding region; and a surface of the light-shielding layer being farthest from the one surface of the base material is positioned farther from the one surface of the base material than a surface of each of the color-filter-forming coloring layers which is on the side opposite to the base material side, and wherein the light-shielding layer arranged in the pixel-dividing light-shielding region has two layers; a first light-shielding layer thereof is arranged to contact the one surface of the base material; segments of the color-filter-forming coloring layers in the respective colors of any adjacent ones out of pixels are each extended to cover the first light-shielding layer; a second light-shielding layer of the two layers is arranged at a surface side of the extended coloring layer segments in the respective colors; and the surface side of the extended coloring layer segments is opposite to the base material side.
