Abstract:
A sheet-like optical member being difficult to damage a shape of a lens part. The sheet-like optical member includes: a substrate; and a lens part, which is formed on the substrate, is made of an active energy ray-curable resin, and has a plurality of unit prisms. The maximum logarithmic attenuation rate ΔE of the lens part measured by a rigid body pendulum method is 0.4 or less.
