Flat panel display with built-in touch sensors

A flat panel display with built-in touch sensors includes 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 is joined together with the first substrate with a liquid crystal layer interposed therebetween. A plurality of touch sensors are at positions adjacent to the respective pixels between the first and second substrates. Each of the touch sensors includes a conductive column spacer on the second substrate, a semiconductor layer in a region on the first substrate, corresponding to the conductive column spacer, and first and second electrodes respectively overlapped with the semiconductor layer in regions at both ends on the semiconductor layer.
