Abstract: It is an object to provide an optical member capable of enhancing efficiency of utilization of light in a liquid crystal display apparatus by laminating a reflective polarizer with an optical layer having another optical function, and it is another object to provide a liquid crystal display apparatus with increased efficiency of utilization of light from a backlight, using the laminated optical member with the reflective polarizer. The present invention provides a reflective polarizer comprising birefringent bodies including polygonal prisms or circular cylinders a shape of a cross section of which perpendicular to a long axis direction is polygonal or substantially circular, which has an aspect ratio of not less than 2, and which has a refractive index difference of not less than 0.05 between a refractive index in the long axis direction and a refractive index in a short axis direction.
