DISPLAY DEVICE WITH TOUCH PANEL, AND METHOD FOR MANUFACTURING DISPLAY DEVICE WITH TOUCH PANEL

WIPO Patent Application WO/2017/014252

A1

A configuration required for detection of a touch position is provided on an active-matrix substrate. A display device with a touch panel is provided with an active matrix substrate 1, a liquid crystal layer, and a counter substrate. On the active matrix substrate 1 are formed: a TFT (display control element) 4; a first insulating film 44 formed on the liquid crystal layer side of the TFT 4; a plurality of pixel electrodes 31 formed on the liquid crystal layer side of the first insulating film 44; a second insulating film 46 formed on the liquid crystal layer side of the plurality of pixel electrodes 31; a plurality of counter electrodes 21 formed on the liquid crystal layer side of the second insulating film 46, the plurality of counter electrodes 21 forming capacitance with the plurality of pixel electrodes 31; a control unit for detecting a touch position by supplying a touch drive signal to the plurality of counter electrodes 21; and a signal line 22 connecting the control unit and the counter electrodes 21, the signal line 22 supplying the touch drive signal from the control unit to the counter electrodes 21. The signal line 22 is formed between the first insulating layer 44 and the second insulating layer 46.
