Abstract:
The present invention relates to a touch panel, more specifically a piezoresistive type touch panel. According to the present invention, it is provided a manufacturing method of a piezoresistive type touch panel, comprising manufacturing a polymer membrane in which a piezoresistive type film pattern, of which resistance varies with applied pressure, is embedded; manufacturing a spacer layer and attaching one side of the spacer layer to a surface of the polymer membrane; and then attaching a bottom substrate to the other side of the spacer layer.
