摘要:
An image input/output apparatus has a photoelectric conversion element, a display element, and a switch element on a substrate, and has a function of displaying an image using the display element by holding a display potential supplied via the switch element in the photoelectric conversion element, and a function of picking up an image by detecting a charge generated in response to light incident on the photoelectric conversion element via the switch element. The photoelectric conversion element is constituted by a first electrode layer, an insulating layer for preventing passage of a carrier of a first conductivity type and a carrier of a second conductivity type different from the first conductivity type, a photoelectric conversion semiconductor layer, an injection prevention layer for preventing injection of the carrier of the first conductivity type to the photoelectric conversion layer, and a second electrode layer. The image input/output apparatus does not require any complicated structure for shielding light, has good display and image pickup characteristics, and allows easy manufacturing processes with low cost.
