Signal line of touch panel display device and method of forming the same

Abstract

A signal line of a touch panel display device includes an upper substrate having 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 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 film is formed, and at least one signal line extending from a side portion of one of the pairs of first electrodes and the pairs of second electrodes to a side surface of the touch panel display device to transmit a signal to an external controller.
