    Abstract: A touchscreen pattern includes detection electrodes, drive electrodes, floating electrodes, and wide detection electrodes. The detection electrodes extend along a first direction and are arranged along a second direction perpendicular to the first direction. The drive electrodes extend along the second direction and are arranged along the first direction to overlap the detection electrodes in a plan view. The drive electrodes and the detection electrodes form capacitors. The floating electrodes are arranged adjacent to the detection electrodes 38, respectively, in the plan view and to overlap the drive electrodes in the plan view. The floating electrodes and the adjacent detection electrodes form capacitors. The floating electrodes and the overlapping drive electrodes form capacitors. The wide detection electrodes are arranged at the outermost with respect to the second direction. The wide detection electrodes have a width larger than a width of the detection electrodes closer to the middle.

    Abstract: 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.
