A gate line and a data line are formed on a base substrate. A first sensor line is parallel with the gate line. A sensor gate electrode is extended from the first sensor line. A sensor active pattern having a plurality of island-type sub-active members is formed on the first sensor gate electrode. A second sensor line is parallel with the data line. A first sensor drain electrode is extended from the second sensor line at the sensor active pattern. A second sensor drain electrode corresponding to the first sensor gate electrode is formed on the sensor active pattern. A pixel electrode is electrically connected to the gate line and the data line. A sensor electrode part electrically connects the first and second sensor drain electrodes spaced apart from the pixel electrode. Light is reflected by the first and second sensor drain electrodes, which have an embossed shape.
