Title: DISPLAY DEVICE INTEGRATED WITH TOUCH PANEL
Abstract:
The present invention provides a display device integrated with a fully in-cell touch panel that can minimize the difference in the wiring resistances of signal lines to supply signals to a common electrode and thereby homogenize the auxiliary capacity in a display area and address the problem of display unevenness or the like. The display device integrated with a touch panel comprises: a plurality of pixel electrodes formed on an active matrix substrate 1; a plurality of common electrodes 21 that create capacitance with the plurality of pixel electrodes; a controller 20 arranged on the active matrix substrate 1 and generating a control signal for the plurality of common electrodes; and a plurality of signal lines 22 that connect the controller 20 to each of the plurality of common electrodes 21. Each signal line 22b, 22c, and 22d among the plurality of signal lines 22 that is connected to a common electrode excluding the common electrode furthest away from the controller 20 includes a folded part 22b1, 22c1 or 22d1 in a region where the common electrode is formed.
