Abstract
The present invention provides an image display unit integrated with a photo-sensor, comprising a photo-sensing element with high sensitivity and low noise and a polycrystalline silicon TFT prepared at the same time on an insulating substrate using planer process. After a first electrodeand a second electrodeof the photo-sensing element are made of polycrystalline silicon film, a light receiving layer (photoelectric conversion layer)of the photo-sensing element is prepared by amorphous silicon film on upper layer. In this case, a polycrystalline silicon TFT is prepared at the same time.
