Abstract
In a touch panel, upper conductive layers on a bottom surface of an upper substrate and lower conductive layers on a top surface of a lower substrate are formed in belt shapes and extend in directions intersecting each other. End portions of the upper conductive layers are connected by an upper resistive layer, and end portions of the lower conductive layers are connected by a lower resistive layer. Then, a voltage is applied between ends of the lower resistive layer and the upper resistive layer sequentially, and voltages at the end portions of the upper resistive layer and the lower resistive layer are detected. Pressed positions can be detected with such a simple configuration.
