Patent ID: 8310648

Claim:
A method of fabricating a liquid crystal display device with sensing function comprising: forming gate patterns including a gate line, a gate electrode of a first switching thin film transistor, a gate electrode of a second switching thin film transistor, a gate electrode of a sensing thin film transistor, and a storage capacitor lower electrode of a storage capacitor on a substrate; forming a gate insulation film on the substrate including the gate patterns; forming a semiconductor layer on the first switching thin film transistor, the second switching thin film transistor and the sensing thin film transistor formed on the substrate including the gate insulation film; forming source/drain electrode patterns including a data line crossing the gate line with the gate insulation film interposed therebetween, source and drain electrodes of the first switching thin film transistor, source and drain electrodes of the second switching thin film transistor, driving source and drain electrodes of the sensing thin film transistor, and a storage capacitor upper electrode of the storage capacitor; forming a first passivation film on the sensing storage capacitor and the second switching thin film transistor; forming a reflective electrode on the first passivation film and overlapping the regions of the storage capacitor and the second switching thin film transistor; forming a second passivation film including a hole to expose the drain electrode of the first switching thin film transistor on the substrate including the reflective electrode; and forming a pixel electrode connected to the drain electrode of the first switching thin film transistor through the hole, wherein the first passivation film is removed on the sensing thin film transistor and the second passivation film contacts with the sensing thin film transistor.
