Patent ID: 7705813

Claim:
A liquid crystal display panel, comprising: a first pixel electrode formed on a first substrate, wherein the first pixel electrode selectively receives a maximum voltage and a minimum voltage; an insulating film formed on the first pixel electrode; a second pixel electrode formed on the insulating film wherein the second pixel electrode receives a positive data voltage and a negative data voltage that are relative to the medium voltage in a range between the maximum voltage and the minimum voltage; a common electrode disposed on a second substrate which is bonded with the first substrate with a liquid crystal therebetween, wherein the common electrode receives a medium voltage between the maximum voltage and the minimum voltage; a thin film transistor that is connected to the second pixel electrode on the first substrate and that supplies the positive and negative data voltages from a drive circuit to the second pixel electrode; a gate line and a data line which are connected to the thin film transistor; and a pad that is connected to the first pixel electrode on the first substrate and that supplies the maximum voltage and the minimum voltage from the drive circuit to the first pixel electrode, wherein the liquid crystal is driven with an alternating current.
