Abstract
Abstract A contact-type color image sensor in which pixel electrodes (2a - 2d) are linearly provided in a main scanning direction and three (or four) rows thereof are arrayed in a subscanning direction, color filters (8a - 8c) for color- separating are provided to oppose the pixel electrodes (2a - 2d), an amorphous semiconductor film (4) is formed on the pixel electrodes (2a - 2d), and a common transparent electrode (5) is formed on the amorphous semiconductor film (4). This color image sensor allows color-separation in the subscanning direction to maximize the areas of pixel electrodes (2a - 2d).
