Abstract
The present invention provides an electrophoretic display in which an insulating liquid is uniformly provided to the divided microspaces each corresponding to one pixel and display characteristics uniform over the display surface are actualized. The present invention includes a transparent first substrate 1 and a transparent second substrate 2 arranged with a predetermined gap therebetween, charged particles 6 dispersed in an insulating liquid 5 provided to the gap, and a first electrode 3 and a second electrode 4 arranged on either of the first substrate 1 and the second substrate 2, wherein liquid-repellency parts 8 and repellency-lowered parts 9 are arranged on the surface of the first substrate 1 and the surface of the second substrate 2, and the insulating liquid 5 is provided to the repellency-lowered parts on the surface of the first substrate 1 and the surface of the second substrate 2.
