A display device comprising a plurality of pixels (200), each pixel comprising charged particles (28) that are movable between storage (20) and active (24) regions of the pixel under the influence of an electric field. The number of charged particles (28) within the active region (24) determines the optical appearance of the pixel, and the storage region (20) is used for storing charged particles (28) away from the active region (24). Each pixel (200) comprises enough charged particles to saturate both the storage and active regions, such that moving additional charged particles to those regions does not significantly affect the optical appearances of those regions. Hence there are always enough charged particles (28) available within the pixel (200) to saturate the active region (24), and the storage region (20) may be saturated even when the active region (24) is saturated.
