1. A home appliance, comprising:
a main body; and
a door configured to open and close the main body, the door including:
a door body, and
an electrophoretic display (EPD) panel disposed on a front side of the door body, the EPD panel including:
a plate configured to cover at least a portion of the front side of the door body and to allow light to pass through,
a first electrode between the plate and the door body and configured to allow light to pass through,
a second electrode between the first electrode and the door body so as to face the first electrode,
an electrophoretic layer between the first electrode and the second electrode, and including a color cell in which first charged particles having a first color and second charged particles having a second color different from the first color are accommodated, the first charged particles and the second charged particles being flowable within the color cell, the second charged particles having a different charge than the first charged particles, and
a protective plate attached to a rear surface of the second electrode and including a material different from a material of the plate, and
a coupling portion coupling the protective plate to the front side of the door body, the coupling portion extending between the protective plate and the front side of the door body so as to contact a portion of the protective plate that is less than an entirety of the protective plate,
wherein the material included in the protective plate has a higher rigidity than the second electrode and the electrophoretic layer so as to distribute a load transmitted from the coupling portion to the electrophoretic layer, and
wherein the plate, the first electrode, the electrophoretic layer, the second electrode, and the protective plate are stacked in a stacking direction, and the coupling portion is coupled to a rear surface of the protective plate in the stacking direction.
