Abstract
A liquid crystal display device for displaying an image by changing orientation of a liquid crystal layer sealed between two substrates includes a lower substrate having a microstructure which outputs light incident on a side surface of the lower substrate to an upper surface of the lower substrate, a light source emitting light to the side surface of the lower substrate, a selective reflection panel provided on the upper surface of the lower substrate to reflect light having a predetermined incident angle or more and transmit the remaining light, and a reflection panel provided under the lower substrate.
