Patent ID: 8159626

Claim:
A liquid crystal display device comprising: a first substrate including a ground line located around the periphery of the first substrate and supplied with a ground voltage, and an extended ground line extending outward from the ground line to the end of the first substrate, and attaching a first polarization plate; a second substrate joining to the first substrate with a sealant and attaching a second polarization plate; and a conductive upper-lower substrate connecting static electricity discharging path connecting to the extended ground line by forming at edges of the first polarization plate and the second polarization plate, and by intruding between the first and the second substrates, wherein the ground line and the extended ground line are made of one of the materials including copper (Cu), aluminum (Al), molbdenium (Mo) and chromium (Cr), and the extended ground line is located flush with the edge of the first substrate to be connected with the static electric discharging path.
