PURPOSE: To avoid generation of smear by arranging position of a contact hole sufficiently apart from end of an electrode so that the contact hole do not give influence on a recess to be formed on surface of an photoconductive film.

CONSTITUTION: On a surface of photoconductive film 15, a recess 20 which corresponds height difference between ends of pixel electrodes 181 and 182 is formed. There are provided contact holes 191 and 192 at more than predetermined distances apart form the pixel electrodes 181 and 182. Therefore, a recess 20 shape formed on the surface of photoconductive film 15 by the height difference between ends of pixel electrodes 181 and 182 becomes independent to height differences of contact holes 191 and 192 thereby the recess produced by the height differences of pixel electrodes 181 and 182 is protected from going out of shape due to influence by height difference of contact holes 191 and 192. Thus, refraction by lens effect of recess 20 can be enhanced so that lights are protected from reaching to chips in lower layers through a gap between the pixel electrodes 181 and 182 so that the generation of smear can positively be prevented.
