Abstract: A method to control a refrigerator includes changing a transparent display assembly to be in a first or transparent state allowing an inner space of the refrigerator to be visible through the transparent assembly, a second or opaque state so as to conceal the inner space, and a third or a display state to display information on a display of the transparent assembly. The transparent display assembly includes a front panel, a rear panel, an outer spacer configured to maintain a first distance between the front panel and the rear panel, a display provided on a rear surface of the front panel, a light guide plate spaced apart from the display, and a first spacer configured to support the light guide plate and to maintain a second distance between the display and the light guide plate.

Abstract: Provided is a refrigerator. The refrigerator includes a cabinet, a door configured to open and close the cabinet and having an opening, a panel assembly configured to shield the opening and including a see-through part, and a light provided further inward from the refrigerator than the panel assembly to illustrate a rear side of a door so that the inside of the refrigerator is visible through the see-through part. The wherein the panel assembly includes a transparent front panel defining a front surface thereof, a display disposed on a rear surface of the front panel, a light guide plate disposed to be spaced apart from the display, a backlight configured to emit light toward an end of the light guide plate, and a rear panel made of a transparent material, spaced apart from the front panel to define a heat insulation space in which the display, the light guide plate, and the backlight are accommodated. The light may emit light to a rear region of the light guide plate from the outside of the light guide plate and be disposed at an angle between a direction parallel to the light guide plate and a rear side crossing the light guide plate.
