Abstract
A lens film including a transparent substrate film and a concave or convex lens layer provided on a side of the substrate film. The lens layer contains a resin composition with conductive fine particles dispersed therein and has a surface resistivity of not more than 10 &OHgr;/□. Another embodiment is a lens film including a transparent substrate film, a conductive layer provided on a side of the substrate film, and a concave or convex lens layer provided on the conductive layer, the conductive layer having a surface resistivity of not more than 10 &OHgr;/□. The lens film can be part of a surface light source where the light-receiving side of the lens film is disposed on the light outlet side. The surface light source can be part of a liquid crystal display device.
