Patent ID: 7701540

Claim:
A liquid crystal display device, comprising: first and second substrates that face each other; a plurality of first column spacers and a plurality of second column spacers formed on the second substrate; a plurality of gate lines on the first substrate; a plurality of data lines formed vertically with respect to the gate lines; and a plurality of thin film transistors formed adjacent to each crossing portion of the gate lines and the data lines; a plurality of protrusions formed at a predetermined portion on the first substrate, wherein the protrusions comprise an upper layer being on the same layer with source/drain electrodes of the thin film transistors and a lower layer being on the same layer with a semiconductor layer of the thin film transistors; and a plurality of compensation patterns formed at another predetermined portion on the first substrate; wherein an end portion of the first column spacer has a wider area than an end portion of the protrusion and an end portion of the compensation pattern has a wider area than the end portion of the protrusion.
