Liquid crystal display device
First Claim
1. A liquid crystal display device for displaying an image by changing orientation of a liquid crystal layer sealed between two substrates, the device comprising:
- 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,wherein the selective reflection panel is configured to reflect the light having an incident angle that is greater than 42°
with respect to a plane perpendicular to the upper surface of the lower substrate.
