Liquid crystal display comprising a reflective polarizing layer including a plurality of microfibers each having an anisotropic refractive index and longitudinally extending in the same direction

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.
