Producing structured surface on substrate, for use as diffuser or reflector for optical applications, e.g. in liquid crystal displays, by structuring then partially smoothing by sol-gel coating process

摘要

Production of a structured surface on a substrate (I) involves (a) structuring (I) and (b) partially smoothing the structuring by a sol-gel coating process to give a diffuse scattering surface. An independent claim is included for the structured surfaced substrate obtained by the process.
