Abstract

A driving circuit for improving display quality of a liquid crystal display (LCD) device. The driving circuit is installed on a surface of a glass substrate of the LCD device and includes a bus line and a plurality of driving IC chips. The driving circuit also includes a plurality of impedance matchers between the bus line and each of the driving IC chips so as to make each driving IC chip obtain equal input voltage from the bus line.
