Abstract

A color-filter substrate assembly 10 includes a substrate 3 b having a rugged surface, a light-shield layer 7 a arranged on the substrate 3 b, and having a rugged surface conformal to the rugged surface of the substrate 3 b, a reflective layer 5 arranged on the light-shield layer 7 a and having a rugged surface conformal to the rugged surface of the light-shield layer 7 a, and a color layer 4 arranged on the substrate 3 b. The light-shield layer 7 a has an aperture 8, and the reflective layer 5 a has an aperture 6, and is covered with the color layer 4. The invention provides a color-filter substrate assembly which is inexpensive, and provides, in the simple structure thereof, excellent functionality with a light-shield function, such as of a black mask, and a scattering function for a reflective-type display when the color-filter substrate assembly is used in an electro-optical device (such as a reflective-type liquid-crystal display device or a transflective-type liquid-crystal display device).
