PROBLEM TO BE SOLVED: To provide a photosensor that suppresses the leakage current of a photodiode. SOLUTION: The photosensor includes: a first passivation film 41 formed in an upper layer of a thin-film transistor 52; an opening which is provided in the first passivation film 41 and electrically connects a drain electrode 13 with a lower electrode 14; a second passivation film 42 which coats the thin-film transistor 52 and the photodiode 51; upper layer wiring 23 which is formed in an upper layer of the second passivation film 42 and electrically connected with an upper electrode 15 via a contact hole provided in the second passivation film 42; and a connection film 16 formed in an upper layer than the upper electrode 14 so that the upper electrode 14 is not exposed when the contact hole is formed.
