ABSTRACT:
An electroscopic fluid display comprises substrates (1, 2) having fixed electrodes (12, 22), and movable electrodes (3) between the substrates, the electrodes (12, 22, 3) being provided on the free main surfaces with an insulating layer (13, 23, 31, 32) respectively, and the asymmetry of the alternating voltage drive for the electrodes being adapted to the difference in surface properties as regards charge delivery and charge adsorption of facing insulating layers (13, 31; 32, 23), or the alternating voltage drive is symmetrical, and facing insulating layers (13, 31; 32, 23) have substantially the same surface properties as regards charge delivery and charge adsorption. The insulating layer (31, 32) consists, preferably, on at least one main surface of the movable electrode (3) of anodized electrode material and continuing along (33) the outer peripheral and inner peripheral portions of the perforated movable electrode 3. The insulating layer on the substrate (1, 2) opposite the insulating layer of anodized metal material (31, 32) on the main surface of the movable electrode (3) consist of an oxide of the same metal material.
