Matrix-Addressable Display Device

摘要

A matrix-addressable display device having a plurality of pixel areas (6) comprises two opposed cell walls (1) enclosing a layer of an electrophoretic composition (4) comprising a liquid crystal material having finely divided particles (5) dispersed therein. A plurality of row electrodes (3) are provided on an inner surface of one cell wall and a plurality of column electrodes (2) on an inner surface of the other cell wall. Each row electrode (3) intersects a column electrode (2) at an intersection area (10) within a pixel area (6) which is switchable from a first optical state to a second optical state by the application of a suitable electric pulse between the electrodes (2,3) at the intersection area. The intersection area (10) is smaller than the pixel area (6). Each electrode (2,3) is made of metal.
