Abstract
A liquid crystal display capable of improving the brightness without depending on the aperture ratio. By setting a lower polarization plate between an array substrate and a color filter substrate, the light reflected from a metal film formed on the array substrate can directly return to a light guide plate. Therefore, the light recycling efficiency is improved and the brightness of the liquid crystal display is improved.
