Patent ID: 7859512

Claim:
An image display panel of the reflection type comprising, in a multilayer structure: a first layer including a periodic planar arrangement of a plurality of electrophoretic elements, each of the plurality of electrophoretic elements included in the first layer showing one of an opaque black state and a transparent state in response to an input signal; and a second layer including a periodic planar arrangement of a plurality of electrophoretic elements, each of the plurality of electrophoretic elements included in the second layer showing at least a first color state and a second color state in response to an input signal, wherein each of the plurality of electrophoretic elements has a drive electrode and a common electrode, and a display state is controlled by an input signal given between the drive electrode and the common electrode, wherein drive electrodes for the electrophoretic elements included in the first layer are smaller in surface area than drive electrodes for the electrophoretic elements included in the second layer, and wherein the electrophoretic elements included in the first layer and the electrophoretic elements included in the second layer are respectively individually controlled.
