Abstract

Disclosed is a display device having touch sensors which may reduce parasitic capacitance and a method of manufacturing the same. The display device includes a plurality of touch sensing lines respectively arranged so as to traverse a plurality of common electrode blocks forming an electric field with pixel electrodes, a lower planarization layer having openings in regions overlapping drain electrodes of thin film transistors, an upper planarization layer arranged between one of the pixel electrodes and the common electrode blocks, and the touch sensing lines so as to cover a side surface of the lower planarization layer, and an upper protective film arranged between the pixel electrodes and the common electrode blocks, and, thus, parasitic capacitance generated between the touch sensing lines and the common electrode blocks may be reduced without reduction in liquid crystal capacitance and storage capacitance.
