1. An image pickup device comprising:
a flexible substrate;
an X-ray sensor comprises a semiconductor layer, and the semiconductor layer comprises an amporphous oxide, arranged on the flexible substrate; and
a field effect transistor for reading a signal from the X-ray sensor, wherein:
the field effect transistor has an amorphous oxide as an active layer; and
the amorphous oxide comprises one of an oxide having an electron carrier concentration of less than 1018/cm3 and an oxide whose electron mobility tends to increase with increasing electron carrier concentration.
