Abstract
A touch sensor module is structured by laminating an organic EL layer and a smoked glass layer on a substrate, which has a positive electrode pattern and a negative electrode pattern on the upper surface. When a driving voltage is applied to the positive electrode pattern, a current flows in a segment between the positive electrode pattern and the negative electrode pattern in the organic EL layer and the segment emits light. The emitted light causes a figure that represents a key to appear on the display surface of the touch sensor module. When the user touches a portion in which the figure representing a key is displayed on the display surface of the touch sensor module, a capacitance between the positive electrode pattern and the negative electrode pattern changes. Accordingly, the user's touch to the figure representing a key is detected.
