Abstract
A reflectance-type liquid crystal display device includes a first light scattering unit on a first substrate, a reflecting layer having a second light scattering unit on a second substrate, and a liquid crystal layer between the two substrates. One of the two light scattering units defines a regular-directional scattering unit which can easily control the reflectance characteristics, and the other light scatterin unit defines a random-directional scattering unit which prevents the light interference caused by the regular-directional scattering unit.
