RESIN COMPOSITION FOR OPTICAL SHEET OPTICAL SHEET AND PROCESS FOR PRODUCING THE OPTICAL SHEET

摘要

the present invention, the shape of the lens is damaged it difficult, also, higher productivity The main purpose is to provide a manufacturable sheet-like optical member. The present invention, is formed on the substrate, the substrate is made of an active energy-ray-curable resin, a sheet-like shape having a lens with a plurality of unit-prism optical element, the maximum is determined by the lens unit body pendulum method logarithmic decrement [Delta] E by providing a sheet-like optical member, characterized in that not more than 0.4, is to solve the above problems. ;
