ABSTRACT:
A screen member for a transmission screen is manufactured by a method including the steps: preparing a microlens substrate, of which the light incident face is formed with a plurality of microlenses; forming a black matrix from a first layer, made by applying a material including a positive photopolymer onto the light emission face of the microlens substrate, on the light emission face of the microlens substrate so that the black matrix has a plurality of openings on light paths of the light that has been transmitted by the microlenses of the microlens substrate; and forming a plurality of light diffusion portions for diffusing the light that has been transmitted by each microlens of the microlens substrate from a second layer, made by applying a material including a negative photopolymer onto the black matrix.
