Abstract
The present invention provides a lenticular sheet in which cylindrical lens parts including a radiation curable resin are formed on one side of a transparent support, and at least a light-diffusing layer and light-blocking stripes are formed on the flat surface located on the opposite side of said sheet. Cylindrical lens parts with a fine pitch of 0.3 mm or less can be obtained; furthermore, finely pitched light-blocking stripes can be accurately formed in the desired positions. A projection screen constructed by combining the aforementioned lenticular sheet with a Fresnel lens sheet is ideally suited for viewing a liquid crystal projection TV with a high image definition.
