PURPOSE:To restrain blooming and smear by laminating a photo transmittance variable element on the photo receiving surface of a substrate. CONSTITUTION:A clear electrode layer 8 is provided above an insulation film 5 at a fixed internval, and the clearance between this insulation film 5 is the clear electrode layer 8 is filled with nematic liquid crystal 9. A fixed voltage is impressed on the substrate and said variable element, thus making the photo transmittance at the position corresponding to each of a plurality of picture elements of said element variable according to the variation of the potential due to the photoelectric conversion of each of a plurality of the picture elements. Thereby, the photo transmittance decreases with the increase of the amount of the incident light, therefore the blooming that a strong light comes incident to some picture element, resulting in the inflow of photo charge flowing out of this picture element into a vertical transfer line, and the smear that the photo charges generated at the substrate bottom in proportion to the amount of the incident light diffuses to said line can be restrained satisfactorily. |
