<p>In order to permit stable gradation display or high-speed display, when predetermined voltages are applied to a collection electrode l and a display electrode 2, respectively, to move particles between the collection electrode 1 and the display electrode 2, a voltage is applied to a pressing electrode 4 to press the particles against the display electrode 2 so that they are stabilized on the display electrode 2 with a uniform spacing therebetween.</p> |
