Abstract
An image sensor includes a plurality of pixel sensing portions arranged in m columns and n rows. Each of the pixel sensing portions includes at least one thin film transistor and a photodetection diode () including n-type (), intrinsic () and p-type () semiconductor layers. The p-type semiconductor layer () includes a multi-layered structure including lower () and upper () p-type semiconductor layered portions. The upper p-type semiconductor layered portion () has a band gap greater than 1.7 eV and has a p-type dopant in an amount not less than two times of that of the lower p-type semiconductor layered portion (). An image sensing-enabled display apparatus and a method of making the image sensor are also disclosed.
