Patent ID: 8259277

Claim:
A liquid crystal display (LCD) device, comprising: 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, wherein a width of the third layer is wider than widths of the first and second layers so as to cover the first and second layers, and is narrower than a width of the column spacer, wherein the pixel electrodes diverged in plurality, common electrodes diverged in plurality are formed on each pixel so as to be aligned alternate with the pixel electrodes.
