Abstract
An electrophoretic display apparatus includes a first substrate and a second substrate; an electrophoretic layer that is allocated between the first substrate and the second substrate; and 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. The first and second electrodes form a comb-teeth shaped electrode in a plan view, which include a plurality of branch portions and a trunk portion combining the plurality of branch portions, and each of first ones of the branch portions, which are located at respective edge portions of a pixel area, has a width smaller than a width of each of second ones of the branch portions, which are branch portions other than the first branch portions.
