Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method for a light shielding layer for a transmission type screen, by which the residue of the light shielding layer for the transmission type screen is reduced and light transmittance of the screen can be improved. SOLUTION: The manufacturing method for the light shielding layer of the transmission type screen includes: a step of applying a black resin solution onto a mold and/or transparent base material; and a step of firmly bonding the mold and the transparent base material together, and curing the black resin solution, thereby transferring the mold pattern to the surface of the transparent base material. In this method, the light shielding layer for the transmission type screen is manufactured by heating the transparent base material at a temperature of Tg>Ts>Tm, wherein Ts is the temperature of the transparent base material, Tg is the glass transient temperature of the transparent base material, and Tm is the temperature of the mold.
