Abstract
An optical sheet combination structure disposed between a polarizer and a surface emitting unit, includes a first optical sheet having a number of columnar cubic structures of curing resin arrayed on a transparent base, a valley portion between adjacent cubic structures contacting a surface of the transparent base, and a second optical sheet disposed nearer to the side of the polarizer than the first optical sheet, having a number of columnar cubit structures arrayed on a surface, and a refractive index of the cubic structures along an extension direction thereof being different from a refractive index of the cubic structures along an array direction thereof.
