Abstract:
1. A signal line of a touch panel display device, comprising: an upper substrate have a first transparent conductive film; a lower substrate having a second transparent conductive film, the lower substrate positioned opposite to the upper substrate; a pair of first electrodes positioned along opposing edges of the upper substrate along a first direction where the first transparent conductive film is formed; a pair of second electrodes positioned along opposing edges of the lower substrate along a second direction perpendicular to the first direction where the second transparent conductive film is formed; an output area at an edge of the display device; a first signal line connected to one of the pair of first electrodes in the output area, and a second signal line connected to the other of the pair of first electrodes; and a third signal line connected to one of the pair of second electrodes, and a fourth signal line connected to the other of the pair of second electrodes; wherein the second signal line substantially overlaps one of the pair of second electrodes; and wherein the third signal line substantially overlaps one of the pair of first electrodes.
