The present invention relates to a display device having a built-in touch input means. The display device comprises: a lower substrate (20) on which a pixel unit (22) consisting of pixels and pixel electrodes is disposed; an upper substrate (30) spaced apart from the lower substrate (20); a plurality of first signal lines (32) and second signal lines (34) arranged on an upper surface or lower surface of the upper substrate (30) to input/output position detection signals; touch cells (60) which are formed in a plurality of sections, respectively, said section being divided from an active region of the upper surface or the lower surface of the upper substrate (30) in which a touch is performed, wherein each of the touch cells (60) has a three-terminal-type switching element (40) connected between the first signal line (32) and the second signal line (34) in each of the sections, and a conductive pad (50) connected to one terminal of the switching element (40); and a touch position detection unit (70) which transmits/receives position detection signals via the first signal lines (32) and the second signal lines (34), and which detects a contact of or access to a touch means (90) by means of the capacitance formed between the touch means (90) and the conductive pad (50) when the touch means (90) is contacted or accessed from the outside of the upper substrate (30), and which acquires a coordinate signal of the touch cell (60) at which a touch input has occurred. |
