Substrate for semi-transmitting type liquid crystal display element and semi-transmitting type liquid crystal display element including the substrate

摘要

A substrate for a semi-transmitting type liquid crystal display element, which is capable of suppressing occurrence of display non-uniformity of the semi-transmitting type liquid crystal display element. A reflective mirror is formed by alternately forming in layers at least one first transparent dielectric film and at least one second transparent dielectric film on a transparent substrate. The first and second transparent dielectric films are different in refractive index from each other. The reflective mirror is formed between a liquid crystal section of the semi-transmitting type liquid crystal display element and the transparent substrate, and the first transparent dielectric film is made of a substantially photocatalytically inactive compound.
