It is an object of the invention to provide an image display apparatus in which noticeability of image persistence of a self-luminous device can be suppressed to a low level without performing an electric control and by a simple configuration. Further disclosed is a diffuse reflective article and optical display utilizing such a diffuse reflector, a method for producing such a diffuse reflector, and a method of improving light reflectivity utilizing such a diffuse reflector. The server can associate the identified appliance with user data associated with the user purchasing the appliance. The system further includes a third elongate member having a third magnet and a spacer positioned distal to the third magnet.
