Abstract
A reflective liquid crystal display device includes first and second substrates spaced apart and facing each other, a gate line and a data line on an inner surface of the first substrate and crossing each other to define a pixel area, a thin film transistor electrically connected to the gate and data lines, a passivation layer covering the thin film transistor, a blocking layer on the passivation layer and corresponding to the thin film transistor, a pixel electrode on the passivation layer and connected to the thin film transistor, a retardation film on an outer surface of the first substrate, a polarizer on the retardation film, an absorption layer on an inner surface of the second substrate, a cholesteric liquid crystal color filter layer on the absorption layer, a common electrode on the cholesteric liquid crystal color filter layer, and a liquid crystal layer between the common electrode and the pixel electrode, wherein the data line overlaps adjacent pixel electrodes and a overlapping width is over 50% of a width of the data line.
