Abstract
A liquid crystal display apparatus includes a backlight unit, a second polarization layer, a liquid crystal layer disposed between the backlight unit and the second polarization layer, a first polarization layer disposed between the backlight unit and the liquid crystal layer. In an embodiment, a surface of the first polarization layer facing the backlight unit includes a reflective surface and a surface of the first polarization layer facing the backlight unit includes an absorbent surface. In another embodiment, the first polarization layer includes grids, which include a metal, and absorbing members, which include dielectric materials. In another embodiment, the first polarization layer includes grids, each of which includes a first component including a dielectric material and a second component including a metal.
