US Patent 9690418 Touch panel and touch panel integrated display device

An electrostatic capacitive touch panel having a large surface area includes (i) a driving electrode group (220) and a sensing electrode group (130) which are provided on a substrate (210), and (ii) a touch panel driving circuit (250) provided in a frame region adjacent to a touch panel region where the driving electrode group (220) and the sensing electrode group (130) are provided. The touch panel driving circuit (250) is made up of TFTs made of an oxide semiconductor having a wide band gap so that the touch panel driving circuit (250) has a small surface area. This allows the touch panel to have a narrow frame.
