Claim:
1. An optical sheet module comprising: a first optical sheet that includes a first base substrate, and a first structurization pattern configured to refract light incident from the first base substrate in a normal direction; a second optical sheet that is formed on the first optical sheet, and includes a second base substrate and a second structurization pattern which refracts the light incident from the second base substrate in the normal direction and intersects an extension direction of the second structurization pattern with an extension direction of the first structurization pattern, wherein a thickness of the second base substrate is formed to be relatively thicker than the thickness of the first base substrate; and a reflective polarizing sheet that is formed on the second optical sheet, reflects light polarized in a first direction to a lower portion, and transmits light polarized in a second direction to a display, wherein the first optical sheet and the second optical sheet are bonded to each other.
