    • A semiconductor device 700 includes a substrate and an optical sensor unit 700 formed on the substrate for sensing light and for generating a sensing signal, the optical sensor unit 700 including a first thin film diode 701A for detection of light in a first wavelength range, a second thin film diode 701B detecting light in a second wavelength range that contains wavelengths longer than the longest wavelength in the first wavelength range. The first thin film diode 701A and the second thin film diode 701B are connected in parallel to each other. The sensing signal is generated based on the output from one of the first thin film diode 701A and the second thin film diode 701B. By this means, the wavelength range that can be detected by the optical sensor unit can be expanded and the sensing sensitivity can be increased.
