LENS SHEET, BACKLIGHT USING THE SAME, AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a lens sheet capable of suppressing side lobe light emitted in the front oblique direction.

SOLUTION: The lens sheet 17 comprises: a base film 21; a lenticular lens resin layer 22; a prism resin layer 23; and a charge resin layer 24. The lenticular lens resin layer 22 is formed on one side surface 211 of the base film 21 and is provided with a plurality of cylindrical lenses arranged side by side to each other. The prism resin layer 23 is formed on the other side surface 212 of the base film 21, is provided with a plurality of prisms arranged side by side to each other and has a refractive index lower than the refractive index of the base film 21. The charge resin layer 24 is charged to the surface on which the prisms of the prism sheet resin layer 23 are arranged side by side and has a refractive index higher than the refractive index of the prism resin layer 23.
