A liquid crystal display employs an on-common storage capacitor which includes a lower storage electrode of a predetermined size provided in the same layer that a signal line is formed, and a pixel electrode provided on the lower storage electrode, and functioning as an upper storage electrode. The system and method enables a first person to transmit product descriptions over a network of computers using an instant messaging system to a second person. The method further comprises forming a charge layer at a surface of the gate insulator, the charge layer having a second polarity, wherein the second polarity is opposite to the first polarity.
