Abstract:
1. A liquid crystal display device including a data line supplied with a data signal, a gate line supplied with a scanning signal, a pixel electrode for driving a liquid crystal cell, and a thin film transistor for applying the data signal to the pixel electrode in response to the scanning signal, the device comprising: a gate insulating film entirely covering the gate line wherein the data line is disposed on the gate insulating film, and wherein the gate line is disposed directly on a substrate; a storage electrode sunken in the gate insulating film to overlap with the gate line, said storage electrode uncovered by and disposed upon said gate insulating film; and a protective layer on the gate insulating film to cover the data line, the gate line and the thin film transistor, wherein a contact hole passes through the protective layer and a portion of the gate insulating film having the storage electrode sunken therein, the pixel electrode is connected to the storage electrode via the contact hole, and the gate insulating film contacts a vertical side surface of the storage electrode.
