Abstract:
1. A photodiode, comprising: a silicon film formed of a continuous grain silicon, wherein the silicon film comprises a first conductivity-type semiconductor region, an intrinsic semiconductor region, and a second conductivity-type semiconductor region opposite to the first conductivity-type, which are arranged in this order along a surface of the silicon film, the intrinsic semiconductor region is formed to be in contact with the first conductivity-type semiconductor region and the second conductivity-type semiconductor region, a distance from a boundary between the intrinsic semiconductor region and the first conductivity-type semiconductor region to a boundary between the intrinsic semiconductor region and the second conductivity-type semiconductor region is set to not less than 2.5 μm and not more than 10 μm, the silicon film is formed on a base of an active matrix substrate comprising a plurality of active elements, and the base is a glass substrate and the silicon film is formed directly on the base.
