Abstract: Provided is an optical sheet module that includes: 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 above the first optical sheet, and includes a second base substrate and a second structurization pattern for refracting the light incident from the second base substrate in the normal direction and intersecting an extension direction of the pattern with an extension direction of the first structurization pattern; and a reflective polarizing sheet that is formed on the second optical sheet, reflects light polarized in the first direction to the lower portion, and transmits light polarized in the second direction to a display, wherein the first optical sheet and the second optical sheet are bonded to each other.
