Patent ID: 8803826

Claim:
A flat panel display with built-in touch sensors comprising: a first substrate having a plurality of gate lines extending in a first direction and a plurality of data lines extending in a second direction and crossing the gate lines, and a plurality of pixels respectively formed in regions defined by the gate and data lines; a second substrate joined together with the first substrate with a liquid crystal layer interposed therebetween; and a plurality of touch sensors at positions adjacent to the respective pixels between the first and second substrates, wherein each of the touch sensors comprises: a conductive column spacer on the second substrate; a semiconductor layer in a region on the first substrate, corresponding to the conductive column spacer; first and second electrodes respectively overlapped with the semiconductor layer in regions at both ends on the semiconductor layer; and a conductive pad on top of the second electrode and configured to contact the column spacer when a downward force is applied to the column spacer.
