Claims17
1-10. (canceled)
An image pickup device comprising:
- a flexible substrate;
- an X-ray sensor 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.
