Abstract:
A liquid crystal display (LCD) device includes a first substrate having a plurality of pixels defined by crossing gate lines and data lines; a second substrate facing the first substrate; a thin film transistor formed at each crossing between the gate line and the data line on each pixel and having a gate electrode connected to the gate line and a source electrode connected to the data line; a pixel electrode formed at each pixel and connected to a drain electrode of the thin film transistor; a plurality of column spacers formed between the first and second substrates and configured to maintain a gap therebetween; and a protrusion formed on the first substrate and overlapped with one or more of the plurality of column spacers, wherein the protrusion includes a first layer made of the same material as an active layer of the thin film transistor and formed on the same layer as the active layer; a second layer made of the same material as the source and drain electrodes of the thin film transistor and formed on the same layer as the electrodes; and a third layer made of the same material as the pixel electrode and formed on the same layer as the pixel electrode.
