Abstract
A transflective liquid crystal display device having a first substrate, a gate line and a data line defining a pixel region by crossing each other on the first substrate, a thin film transistor connected to the gate line and the data line, a passivation layer covering the thin film transistor and having a first transmission hole, a reflector disposed on the passivation layer in the pixel region and having a second transmission hole, a color filter formed on the reflector, a pixel electrode made of a transparent conductive material formed on the color filter and connected to the thin film transistor through a contact hole, a second substrate spaced apart from the first substrate, a common electrode formed of a transparent conductive material and disposed beneath the second substrate, and a liquid crystal layer provided between the pixel electrode and the common electrode.
