This paper proposes an MIM-Diode LCD using SCAD("Storage Capacitor Addressed Diode") structure, and confirms the realization of a large area and high-resolution SCAD-LCD panel by fabricating an LCD panel with 450 X 450 pixels and 0.2 mm pitch. A characteristic for the "SCAD" structure is that the series connection between an MIM-diode and a storage capacitor is addressed by column and row electrodes. The voltage applied to a liquid-crystal layer is controlled by the storage capacitor voltage. "SCAD-LCD" advantages are that fine lithography and fine alignment accuracy are unnecessary, even for fine-pitch panels, due to the large storage capacitor capacitance. These advantages are also confirmed by digital simulation.
