Substrate for reflection type liquid crystal display element |
摘要 |
A substrate for reflection type liquid crystal display elements is provided, which has a multilayer dielectric film (reflective mirror) which can have fewer layers than according to the conventional art and can thus be formed in a shorter time, and which can stably obtain an optical characteristic of a desired flatness across the visible region, and moreover can prevent the occurrence of coloring due to reflection. The reflective mirror is formed on top of a transparent substrate, and is comprised of a predetermined number of high-refractive-index first transparent films and low-refractive-index second transparent films laminated alternately on the transparent substrate. Either or both of the first transparent films and the second transparent films are arranged such that the film thickness thereof increases progressively or decreases progressively with distance from the transparent substrate.
