PROBLEM TO BE SOLVED: To provide a method for producing a lens sheet, in which control of a lens pitch having extremely high precision can be performed. SOLUTION: In the method for producing the lens sheet, an activation energy beam curing composition is injected between the lens pattern forming face of a cylindrical lens mold, in which the lens pattern has been formed, and a light-transmissive base material. Activation energy beam is irradiated in such a state that the activation energy beam curing composition is sandwiched between the light-transmissive base material and the cylindrical lens mold and the same is cured and a lens is formed on one side of the light-transmissive base material. Tension is given to the light-transmissive base material in such a state that it comes into contact with the cylindrical lens mold through the activation energy beam curing composition and also the pitch of the lens pattern of the cylindrical lens mold is previously corrected in correspondence with the given tension. |
