Patent ID: 7773177

Claim:
A liquid crystal display device, comprising: a first substrate; a second substrate substantially parallel to the first substrate; a plurality of gate and data lines crossing each other on the first substrate and defining a pixel region; a thin film transistor near a crossing portion of the gate and data lines; a color filter pattern corresponding to the pixel region; a pixel electrode corresponding to the pixel region; and a black matrix disposed on the thin film transistor and including carbon particles coated with an insulating material and metallic titanium particles, the black matrix having an impedance equal to about 10 5 Ω or more, a specific resistance equal to about 10 11 Ωcm or more, and a relative dielectric constant equal to about 20 or less at a driving frequency between about 1 kHz and 100 kHz, wherein the black matrix includes a color pigment, and wherein the black matrix further includes at least one of bromine (Br) and chlorine (Cl).
