  • Patent number: 4910579
    Abstract: A semiconductor integrated display is disclosed herein in which a matrix of conductive display electrodes is formed over a corresponding matrix of switching devices which are integrated in a single crystal semiconductor chip such that the display electrodes are connected to their respective switching devices through respective conductive paths. The display electrodes are divided into a plurality of subsets each of which is formed in respective layers, so that the display electrodes of an upper subset overlap the edges of the display electrodes of the lower subset. The display electrode layers are separated by intermediate layers of electrically insulating material. The conductive paths from each higher layer subset passes through gaps between electrodes of any lower subset and through the insulating layers to connect their respective electrodes to the corresponding switching devices.
