ABSTRACT:
A touch panel includes a first touch panel substrate; a second touch panel substrate disposed opposite the first touch panel substrate; at least one surface acoustic wave generator that generates a surface acoustic wave propagating across a surface of the second touch panel substrate facing the first touch panel substrate in a predetermined direction; at least one surface acoustic wave sensor that senses the surface acoustic wave generated by the surface acoustic wave generator; a position detector that detects a position where the first touch panel substrate is pressed according to the waveform of the surface acoustic wave sensed by the surface acoustic wave sensor; and spacers disposed between the first and second touch panel substrates along a path where the surface acoustic wave propagates from the surface acoustic wave generator to the surface acoustic wave sensor.
