To provide a color filter substrate for an organic electroluminescent element capable of removing contamination existing on the surface, and a method of manufacturing the color filter substrate for the organic EL element with a high yield removing the contamination without damaging the surface of the color filter substrate.

The color filter substrate 1 for the organic EL element is provided with a substrate 2, a coloring layer 3 formed on the substrate 2, an overcoat layer 4 formed on the coloring layer 3, an inorganic layer 5 formed on the overcoat layer 4, an element-forming area 11, and a surplus cut-off area 12 that can be cut off arranged at an outer periphery of the element-forming area 11. The inorganic layer 5 is provided at the element-forming area 11 as well as the cut-off area 12.
