PHOTODIODE, DISPLAY DEVICE PROVIDED WITH PHOTODIODE, AND METHODS FOR MANUFACTURING THE PHOTODIODE AND THE DISPLAY DEVICE

摘要

A photodiode (10) is provided with a p-type semiconductor region (11), an i-type semiconductor region (12) and an n-type semiconductor region (13). A protection film (9) provided on the surface of the photodiode is removed from at least a light receiving portion of the photodiode (10). The photodiode (10) which has less characteristic changes even the photodiode is used for a long period of time, and a display device using the photodiode (10) are provided.
