Patent ID: 8427606

Claim:
A liquid crystal display comprising: a light source generating a light; a liquid crystal display panel comprising a pixel including a plurality of sub-pixels, the liquid crystal display panel receiving the light from the light source to display images thereon; and a reflective polarizer arranged between the light source and the liquid crystal display panel to transmit or reflect the light according to a direction in which the light vibrates, wherein the reflective polarizer comprises: a reflective polarizing layer including a plurality of microfibers each having an anisotropic refractive index within the reflective polarizing layer, each of the plurality of microfibers longitudinally extending in a same direction with respect to each other; and a protective layer having an isotropic refractive index and overlapping the reflective polarizing layer, wherein a thickness of the reflective polarizing layer of the reflective polarizer is between about (2,000 micrometers−a pixel pitch)×0.01 and about, (2,000 micrometers−a pixel pitch)×0.1, and the pixel comprises two adjacent sides extending in different directions from each other, and the pixel pitch is defined by a length of one of the two adjacent sides.
