ABSTRACT:
A liquid crystal display device of the active matrix kind having an array of picture elements (10) defined by opposing electrodes (34;45,14), carried on respective supporting plates (20,22) with switching elements (16), such as two terminal bidirectional diode structures, arranged serially between address lines (12) and one set of picture element, PE, electrodes on one plate, in which the one set of PE electrodes overlie the address lines with the switching elements disposed therebetween, thus allowing close packing of the elements. For transmissive mode operation the PE electrodes and address lines, and maybe the switching elements, are transparent. A high degree of fault tolerance is obtained by providing a plurality of switching elements for each picture element, and dividing each of the one set of PE electrodes into a plurality of sub-electrodes, each associated with a respective one or more switching elements. The switching elements may be capacitively coupled to the PE electrodes. The device may further include conductive layers on the one plate forming storage capacitors associated with the picture elements and serving to screen the PE electrodes.
