摘要： PROBLEM TO BE SOLVED: To solve the problem that since a capacitance coupling type touch panel detects a position by acquiring change in capacitance between a fingertip and a position detection electrode, change in surface static electricity is unlikely to be changed to fail in detecting the position when a touch is made with a complete insulator, and input ends in failure because of no change in capacitance with the position detection electrode when a touch is made with a resin-made pen or other insulators.SOLUTION: The capacitance coupling type touch panel includes an electrode circuit which detects position coordinates on a transparent substrate, and also has a floating electrode at an isolated position opposed to an XY position coordinate electrode. Then the capacitance coupling type touch panel is adapted to a pen input function by having a function of detecting a position touched with a pen by causing capacitance coupling between the floating electrode and XY position coordinate electrode as the floating electrode is touched with the pen to be put closer to the XY position coordinate electrode.

摘要： PROBLEM TO BE SOLVED: To provide a highly durable capacitive coupling touch panel with high visible light transmittance that responds to a finger input as well as a touch by a non-conductive input means.
SOLUTION: There are provided coordinate detection electrodes for detecting XY position coordinates, and a transparent Z electrode. The Z electrode is arranged at a certain distance with a spacer interposed therebetween. An elastic layer is deformed along the spacer due to compression by the touch to depress the Z electrode. The distance between the Z and X electrodes and that between the Z and a Y electrodes are reduced, and capacitance is increased, thereby enabling change detection in capacitance among the X, Y, and Z electrodes (where a distance between the electrodes is changed due to depression) even by the non-conductive input means to detect the coordinates of the touch position.
