Abstract
A transistor () which acts as a load-current source for a source follower amplifying transistor () for outputting a pixel signal to a pixel output line () is provided in each picture element (), whereby a high bias current is prevented from passing through the high-resistance pixel output line (), so that a variation in an offset voltage among picture elements is suppressed. Inclusion of the high-resistance pixel output line () into the source follower amplification circuit is also avoided, whereby the gain characteristics are prevented from deterioration. Thus, the S/N ratio of the picture element is improved so as to enhance the quality of the images.
