ABSTRACT:
A matrix liquid crystal display device of the kind having a light shielding matrix (18) in the form of a grid of electrically conductive material carried on the same plate (11) as one set of address conductors (20) and separated therefrom by an insulating layer (21), further includes a conductive band (30) which extends around and contacts the periphery of the grid (18) and exhibits less resistance per unit length than the portions (19) of conductive material constituting the grid, and which is connected at a plurality of points to a predetermined potential, e.g. ground, whereby cross-talk effects due to capacitive couplings between the matrix and the address conductors are reduced.
