Abstract
A device for picking up or displaying images includes a semiconductor device having at least one cold cathode. The semiconductor device is mounted to the outside of the device for picking up or displaying images by being fixed to a support having an opening to permit the passage of electrons from the semiconductor device to the interior of the devices for picking up or displaying images. This mounting configuration offers the advantages of simple cooling of the semiconductor device, direction connection of the semiconductor device, and improved electro-optical performance.
