PROBLEM TO BE SOLVED: To provide a lenticular lens sheet superior in contrast performance, regardless of the size of the pitch of lenses with which the lenticular lens sheet is equipped. SOLUTION: The lenticular lens sheet 10 is equipped with a 1st lens unit 12 condensing incident light in a prescribed direction, a 2nd lens unit 13 condensing the light in a direction nearly orthogonal to the condensing direction of the 1st lens unit 12, and a light-shielding layer 17 formed on a light-emitting side from the 1st and the 2nd lens units 12 and 13. Aperture parts 18 through which the incident light passing through the 1st and the 2nd lens units 12 and 13 can pass are formed on the light-shielding layer 17, and are equipped with incident light passing parts A corresponding to shape to make the incident light pass, and coupling parts B coupling the mutually adjacent incident light passing parts out of them in the prescribed direction.
