PROBLEM TO BE SOLVED: To provide an inexpensive touch panel capable of color imaging with high resolution.SOLUTION: A touch panel includes a panel including a first substrate and a second substrate opposed to each other, and a plurality of light sources sequentially or concurrently providing, from the first substrate side, lights of different wavelength regions to the panel. A plurality of pixels each including a liquid crystal element, a photodiode, and a thin film transistor are provided between the first substrate and the second substrate. An island shaped semiconductor film included in the photodiode and an island shaped semiconductor film included in the thin film transistor are formed by etching one semiconductor film on the second substrate. |
