The optical sheet includes a first lens sheet having a plurality of first three-dimensional structures arrayed to extend to one surface thereof, and a reflective polarizer sheet for transmitting either one of p-polarization component and s-polarization component of incident light and reflecting the other of p-polarization component and s-polarization component of the incident light. Head portions of the first three-dimensional structures are bonded to the reflective polarizer sheet.
