Abstract:
1. An electrophoretic display apparatus comprising: a first substrate and a second substrate; an electrophoretic layer that is allocated between the first substrate and the second substrate, and includes particles having first color, particles having second color, and a dispersion medium; a first electrode and a second electrode that are each formed in an island shape, for each pixel, at the electrophoretic layer side of the first substrate, and are mutually independently driven; and a common electrode that is formed at the electrophoretic layer side of the second substrate, and is larger than a total area of the first electrode and the second electrode, wherein the first electrode forms a comb-teeth shape electrode in plan view including a plurality of first branch portions and a first trunk portion that connects the plurality of first branch portions, the plurality of first branch portions including a first edge branch portion that is located at a first edge portion of a pixel area and has a width smaller than a width of each of the remaining first branch portions; the second electrode forms a comb-teeth shape electrode in plan view including plurality of second branch portions and a second trunk portion that connects the plurality of second branch portions, the plurality of second branch portions including a second edge branch portion that is located at a second edge portion of the pixel area and has a width smaller than a width of each of the remaining second branch portions; and the plurality of first branch portions and the plurality of second branch portions are aligned in one direction.
