Abstract
A lenticular lens sheet that is bonded to a front faceplate and used in a rear projection type screen is disclosed. The lenticular lens sheet has a plurality of lenticular lenses arranged on one surface of a light-transmitting substrate, and projecting non-convergence parts arranged on the other surface of the light-transmitting substrate in positions different to positions of convergence of light from the lenticular lenses. An external light absorbing layer that absorbs external light is provided on a summit portion of each of the projecting non-convergence parts. Also, the lenticular lens sheet and the front faceplate are bonded together at the summit portions of the projecting non-convergence parts using an adhesive, and the width of adhesive layers formed through curing of the adhesive is less than the width of the external light absorbing layers. Consequently, the adverse effects caused by blockage of light are prevented.
