Patent ID: 6862055

Claim:
A liquid crystal display device having upper and lower substrates, comprising: a display area including gate lines, data lines, and thin film transistors, the gate lines arranged in a direction, the data lines arranged a direction perpendicular to the gate lines, the thin film transistors arranged near cross points of the gate lines and the data lines, wherein the gate and data lines are formed on the lower substrate; a gate pad portion having a plurality of gate pads, each of the plurality of the gate pads connected with the corresponding gate lines; a data pad portion having a plurality of data pads, each of the plurality of the data pads connected with the corresponding data lines; and a gate light shielding pattern formed at the same time as the gate lines and a data light shielding pattern formed at the same time as the data lines, and the gate and data light shielding patterns are between outside edges of the display area and the gate and data pad portions on the lower substrate, and, the gate and data light shielding patterns blocking light during a back-side exposure.
