ABSTRACT:
A liquid crystal display device including a substrate, a thin film transistor provided at an area adjacent to an intersection of a gate line and a data line on the substrate, a protective layer provided on the substrate to cover the thin film transistor, a pixel electrode provided on the protective layer and connected through the protective layer to the thin film transistor, a first hole in a surface of the pixel electrode and positioned above an adjacent gate line and a spacer positioned within the first hole. A method of fabricating a liquid crystal display device includes the steps of forming a thin film transistor at an area adjacent an intersection between a gate line and a data line on a substrate, forming a protective layer covering the thin film transistor, forming a pixel electrode provided on the protective layer and passing through the protective layer to be electrically connected to the thin film transistor, defining a hole in a surface of the pixel electrode by patterning the pixel electrode on the protective layer above an adjacent gate line and depositing a spacer into the first hole using an ink-jet device.
