Abstract
In an active matrix display device integrated with peripheral drive circuits, an image sensor is provided on the same substrate as a pixel matrix and peripheral drive circuits. The image sensor is formed on the substrate having pixel electrodes, pixel TFTs connected to the pixel electrodes and CMOS-TFTs for driving the pixel TFTs. The light receiving unit of the image sensor has light receiving elements having a photoelectric conversion layer and light receiving TFTs. These TFTs are produced in the same step. The lower electrode and transparent electrode of the light receiving element are produced by patterning the same film as the light shielding film and the pixel electrodes arranged in the pixel matrix.
