Abstract
A permeable image display screen having a lenticular lens sheet including a plurality of semi-cylindrical lens portions and a plurality of non-focusing portions. The lens portions are arranged in parallel with spaces on a side of an image light emission surface of the lenticular lens sheet and contain diffusion particles for diffusing image light incident from an image light incidence surface of the lenticular lens sheet. Each of the non-focusing portions, through which the image light does not pass, is arranged on the side of the image light emission surface and between two adjacent lens portions. A glossy permeable layer is provided on the image light emission surface of the lenticular lens sheet.
