ABSTRACT:
An LCD device and a method for manufacturing the same are disclosed, wherein it is possible to reduce an ohmic contact between a reflective electrode and a transparent electrode and to simplify process steps. In the LCD device having first and second substrates and a liquid crystal layer between the first and second substrates, the LCD device includes a gate electrode and a first electrode of a storage capacitor on the first substrate; a first insulating film on the entire surface of the first substrate including the gate electrode; a semiconductor film, source/drain electrodes and a second electrode of the storage capacitor on the first insulating film; a second insulating film on the first insulating film including the source/drain electrodes; a reflective electrode on the second insulating film to connect the drain electrode with the second electrode of the storage capacitor; and a transparent electrode connected with the drain electrode on a third insulating film formed on the second insulating film including the reflective electrode.
