Abstract
A transflective liquid crystal display device including: first and second transparent substrates facing each other with a reflective portion and a transmissive portion; gate and data lines over the first transparent substrate perpendicularly crossing each other and defining pixel regions; a thin film transistor connected to the gate and data lines in the pixel region; an insulator in the thin film transistor on the first substrate covering the gate line; a passivation layer in the reflection portion on the insulator and on the thin film transistor; a pixel electrode in the reflective and transmissive portions, wherein the pixel electrode contacts both the passivation layer in the reflective potion and the insulator in the transmissive portion; a reflector on the pixel electrode in the reflective portion; color filters on a rear surface of the second transparent substrate, the color filters having through holes; column spacers formed between the reflector and the color filters, each column spacer corresponding in position to each through hole; a common electrode under the color filters; and a liquid crystal layer interposed between the common electrode and the pixel electrode.
