PURPOSE:To inhibit the generation of an alias signal with the variation of a well without altering substrate structure while preventing the generation of a novel false signal by forming a well electrode in a picture element array. CONSTITUTION:Points constituting a picture element by a vertical scanning line 46, a vertical signal line 45, an opening section 48 and an active region 43 is made the same as conventional devices, and well electrodes 44 and wirings 47 for fixing the potential of the well electrodes 44 at well potential are added at every picture element. Accordingly, the well electrodes 44 are shaped at every picture element, thus inhibiting the generation of a false signal with the variation of a well without changing substrate structure. |
