Abstract
To eliminate a distortion of an output image detected by a semiconductor device serving as an anode in an electron tube, a faceplate is configured to a planar shape and a window provided on the semiconductor device has a pincushion outer profile in which points on the outer profile of the window that correspond to points on the outer profile of the faceplate are outwardly positioned farther than the corresponding points in the outer profile of the faceplate that are apart from the center of the faceplate. Further, the window is divided into a plurality of segments to define picture elements.
