Abstract
Disclosed is a reflection type liquid crystal display device. A second substrate () is provided opposite to a first substrate () where pixels are formed. A liquid crystal layer () is interposed between the first and second substrates. A reflection electrode () is formed on the first substrate (). The reflection electrode () includes first and second regions () having relatively high and low heights so as to scatter a light, respectively. The first regions () have first widths in a first direction wider than second widths in a second direction so that a reflectivity in the first direction is higher than a reflectivity in the second direction. The widths of the grooves () are varied in a desired direction regardless of shapes of the lenses (), to thereby improve the viewing angle and reflectivity of the display in the specific direction.
