Patent ID: 7733325

Claim:
An electrophoretic display apparatus comprising: a first substrate and a second substrate which are placed opposite mutually; an electrophoresis dispersing liquid which holds charged migration particles and fills between the first substrate and the second substrate; and a first electrode and a second electrode which are located in a pixel of the electrophoretic display and generate an electric field in the electrophoresis dispersing liquid according to a voltage applied, and whose display state is made to be a planar distribution state of the charged migration particles in the pixel in view of a direction perpendicular to the first substrate or second substrate, wherein the first electrode and the second electrode are located in an end portion of the pixel in view of a direction perpendicular to the first substrate or second substrate, and wherein a first planar distribution state that the charged migration particles spread on the first substrate or second substrate from the first electrode toward the second electrode, and a second planar distribution state that the charged migration particles spread on the first substrate or second substrate from the second electrode toward the first electrode are formed alternately, and the charged migration particles are changed into the second planar distribution state from the first planar distribution state without transferring the charged migration particles to an end portion of the second electrode, and the charged migration particles are changed into the first planar distribution state from the second planar distribution state without transferring the charged migration particles to an end portion of the first electrode.
