Patent ID: 7446842

Claim:
A liquid crystal display (LCD) panel comprising: a liquid crystal panel in which liquid crystal is filled between upper and lower substrates and the liquid crystal is in communication with a display electrode and a common electrode which face each other; a first driving circuit connected to the liquid crystal panel by a plurality of data lines and which applies a data signal to the liquid crystal panel; a second driving circuit connected to the liquid crystal panel by a plurality of gate lines and which applies a scan signal to sequentially apply the data signal to the liquid crystal panel; an electrode pad unit which applies an alignment signal voltage to the liquid crystal panel for alignment of the liquid crystal filled in the liquid crystal panel; a first switching circuit which performs a switching operation to apply the alignment signal voltage applied via the electrode pad unit to the liquid crystal panel via the data lines; a second switching circuit which performs a switching operation to apply the alignment signal voltage applied via the electrode pad unit to the liquid crystal panel via the gate lines, and first and second buffer circuits, which prevent the alignment signal voltage from being applied to the first and second driving circuits, wherein the electrode pad unit is directly connected to the first switching circuit and the second switching circuit.
