1. A touch panel display, comprising:
a touch sensor including a first sensor electrode and a second sensor electrode;
a display portion arranged with a plurality of pixels;
a first driving circuit to drive the display portion and a second driving circuit to drive the touch sensor;
a first transparent resin layer covering the touch sensor;
a second transparent resin layer between the touch sensor and the display portion, the first driving circuit, and the second driving circuit;
a sealing layer arranged on an opposite side of the display portion, the first driving circuit, and the second driving circuit from the touch sensor side, covering the display portion, the first driving circuit, and the second driving circuit; and
a transparent shield electrode arranged between the touch sensor and the display portion, the first driving circuit and the second driving circuit, wherein
the first sensor electrode is electrically connected with a plurality of diamond electrode patterns arranged in a first direction,
the second sensor electrode is electrically connected with a plurality of diamond electrode patterns arranged in a second direction intersecting the first direction,
the second sensor electrode is electrically connected to the second driver circuit by drawn wiring by a contact hole arranged in the second transparent resin layer,
the contact hole is sandwiched between the first transparent resin layer and the sealing layer, and
the first sensor electrode and the second sensor electrode are intersected across an inorganic insulating layer.
