Touch panel, display device including the touch panel, and method of manufacturing the touch panel

摘要

An internal connecting terminal (33) includes a first interconnect layer (34A) formed of a same film as a first conductive pattern for touch position detection under an interlayer insulating film (23), and a second interconnect layer (34B) formed of a same film as a second conductive pattern for touch position detection on the interlayer insulating film (23). The first and the second interconnect layers are electrically connected to a lead line (31) at a portion overlapping the lead line (31), and electrically connected together at a portion outside the lead line (31).

1. A touch panel comprising:
a touch region configured to detect a touch position touched by a contact body; a terminal region provided outside the touch region and connected to an external circuit; a first conductive pattern configured to provide touch position detection located in the touch region and made of transparent conductive oxide; an interlayer insulating film provided to cover at least a portion of the first conductive pattern; a second conductive pattern configured to provide touch position detection provided on the interlayer insulating film and made of transparent conductive oxide; a protection insulating film provided to cover the second conductive pattern; a lead line drawn from the touch region to the terminal region, and covered by the insulating film; and an internal connecting terminal connected to at least one of the first conductive pattern or the second conductive pattern, and connected to a lead base end of the lead line, wherein the internal connecting terminal includes a first interconnect layer formed of a same film as the first conductive pattern, and a second interconnect layer formed of a same film as the second conductive pattern, the first and the second interconnect layers being electrically connected to the lead line at a portion of the touch panel overlapping the lead line and being electrically connected together at a portion outside the lead line.
