1. An In-plane switching (IPS) mode LCD device comprising:
first and second substrates opposite each other, each substrate having an active region
and a dummy region;
gate and data lines substantially perpendicular to each other;
a pixel electrode and a common electrode in the active region of the first substrate;
a black matrix layer in the dummy region of the second substrate;
a UV-hardening sealant at a peripheral area surrounding the black matrix layer between the first and second substrates, wherein the UV-hardening sealant bonds the first and second substrates together;
a metal pattern between the UV-hardening sealant and the first substrate; and
a liquid crystal layer between the first and second substrates bonded by the UV-hardening sealant,
wherein the metal pattern completely overlaps the UV-hardening sealant at opposing sides of the sealant at the peripheral area at two edges of the first substrate.
