Abstract
A panel for a liquid crystal display device has a ceramic substrate, lead conductors on the ceramic substrate, an insulating glass layer over the lead conductors and the ceramic substrate, rear segment electrodes on the glass layer which are electrically connected to the respective lead conductors, a transparent glass plate spaced from the rear segment electrodes by a spacer enclosing the space, and transparent front electrodes on the transparent glass plate and facing the rear segment electrodes. The front and the rear segment electrodes are energized for exciting a liquid crystal within the space. This invention also provides a method of making the panel. The main feature of this invention is to use the ceramic substrate and to form the lead conductors on the ceramic substrate, which conductors are electrically connected to the rear segment electrodes on the glass layer, thereby enabling easy manufacturing and contributing to uniform and efficient display.
