Abstract:
1. A method for manufacturing a pattern of a light shielding layer, comprising: a photocatalyst containing layer side substrate preparing process of preparing a photocatalyst containing layer side substrate having a base material and a photocatalyst containing layer containing a photocatalyst; a pattern forming body substrate preparing process of preparing a pattern forming body substrate having a property changing layer of which property on its surface is changed by the action of a photocatalyst in the photocatalyst containing layer; a wettability pattern forming process in which, after placing the photocatalyst containing layer side substrate so as to have a distance of 0.2 μm to 200 μm between the photocatalyst containing layer and the property changing layer, a wettability pattern comprising a lyophilic region and a liquid repellent region is formed on the surface of the property changing layer by irradiation with energy from predetermined direction; a light shielding layer composition coating process of adhering a light shielding layer composition only to the lyophilic region by coating the light shielding layer composition onto the whole surface of the pattern forming body substrate on which the wettability pattern is formed; and a light shielding layer forming process of solidifying the light shielding layer composition adhered to the lyophilic region of the wettability pattern to obtain a pattern of a light shielding layer.
