Patent ID: 7230757

Claim:
A lenticular sheet, which comprises a lenticular lens section having a plurality of cylindrical lenticular lens disposed at one side, and a light-transmittable irregular section having a plurality of protrusions and depressions and disposed t the other side, wherein each of the depressions of the irregular section is disposed in the position corresponding to a point on which a focus of each lenticular lens is formed, a light-absorbing layer is formed at the protrusions of the irregular section, and the depressions of the irregular section are filled with a light-transmittable resin, thereby forming a light-transmittable resin section; wherein a distance F from a straight line connecting both end points of each lenticular lens to a focus of each lenticular lens satisfies the relation of P ⁡ ( L + h ) 2 ⁢ P - d ≦ F ≦ PL d , wherein P is the width of a lenticular lens; L is the distance from a straight line connecting both end points of each lenticular lens to the protrusions of the irregular section; h is the thickness of the light-absorbing layer; and d is the width of the protrusions of the irregular section.
