Abstract
A contact-type color image sensor in which pixel electrodes are linearly provided in a main scanning direction and three (or four) rows thereof are arrayed in a subscanning direction, color filters for color-separating are provided to oppose the pixel electrodes, an amorphous semiconductor film is formed on the pixel electrodes, and a common transparent electrode is formed on the amorphous semiconductor film. This color image sensor allows color-separation in the subscanning direction to maximize the areas of pixel electrodes.
