ABSTRACT:
A compact liquid crystal display of the type wherein a pixel array formed of liquid crystal material is addressed by an associated array of MOSFET circuits, each circuit including a switching device and an overlying storage capacitor. A plurality of substantially parallel gate buses located orthogonal to and insulated from a plurality of parallel drain diffusions are provided for the application of control and video data to the array. A layer of metallization, located within the backplate, forms a common ground plate for the capacitors of the array, shielding the drain diffusions from incident light and thereby eliminating the need for space-consuming diffusion-to-conductor contact regions.
