Abstract
A method of producing a transmissive screen having a structure including light-absorption-material patterns formed on locations corresponding to locations of lens members, which are provided side by side on a light-transmissive substrate, and to locations of boundary portions between the corresponding lens members. In the method, lens compositions are discharged onto and are caused to land on the light transmissive substrate, and, by drops of the lens compositions, very small lens members or precursors thereof are formed. It is possible to provide a method of producing a transmissive screen, which makes it possible to realize at a low cost a bright transmissive screen which has high contrast ratio and which can display a high-quality image having no moiré and no speckles.
