Abstract
The present invention provides a touch panel with features enabling the external form to be downsized without degrading a detection accuracy of a touch input area and applying an electric voltage to a pair of the electrodes and detecting the output electric voltages inverting the polarity of the voltage. A touch panel of the present invention uses the principle of Apollonius' circle for the touch position detection. Said touch panel is fabricated so that two substrates having a transparent conductive film thereon are place in a manner that said each transparent conductive film is facing each other. A first substrate has one electrode and a second substrate has two pairs of point electrodes. Said two pairs of the point electrodes are arranged in a circumference region of said second substrate. An insulation layer is formed in said circumference region excluding the region where said two pairs of the point electrodes are formed, and wirings extracting said two pairs of the electrodes outwards are formed on said insulation layer and arranged in the region inner than said two pairs of point electrodes are formed.
