Abstract
An electro-optic display comprises a two dimensional array of liquid crystal cells (C11A,B to C44A,B) each switchable by means of electrical signals applied to respective pairs of address lines connected to the cell by respective transistors (T11-T44). Each main electrode of each transistor is isolated from the rest of the array by a respective cell of the array.
