Light-shielding layer, method for producing same, and method for producing substrate

摘要

A light-shielding layer including a light-shielding material containing a grafted carbon material, light-shielding material being electrodeposited to form the light-shielding layer, a method for producing a light-shielding layer including a step of electrodepositing a coating material containing a grafted carbon material on a electrode, and a method for producing a substrate having a light-shielding layer including the steps of (1) forming a photosensitive coating film on a transparent electrically conductive layer formed on a transparent substrate, (2) exposing a predetermined area of the photosensitive coating film to light, (3) removing and developing the photosensitive coating film for exposing the transparent electrically conductive layer, and electrodepositing a coating material containing a grafted carbon material on the exposed transparent electrically conductive layer for forming the light-shielding layer, and (4) heating said substrate thus obtained.
