In matrix (X-Y) addressed display devices, the inclusion of a non-linear blocking layer between one or both electrodes and the imaging layer (for example, liquid crystalline layers, electrophoretic layers, photoelectrophoretic layers, etc.) is proposed. The non-linear blocking layer is ohmic at low fields and at some higher field value its resistance drops sharply. Phenoxy, zinc sulfide and other non-linear blocking layers are suitable.
