Provided is a refrigerator, which includes a refrigerating compartment, a freezing compartment, and a door assembly. The freezing compartment is adjacent to the refrigerating compartment. The door assembly selectively opens the refrigerating compartment and the freezing compartment. The door assembly includes a glass member defining a frontal exterior thereof and allowing an inside of the refrigerating compartment or the freezing compartment to be seen therethrough when the door assembly is closed, a deposition treated layer formed on a rear surface of the glass member to allow light to partially pass through the glass member, and a transparent plate spaced a predetermined distance from the glass member. Gas for insulation is injected in a space formed between the glass member and the transparent plate, and the space is sealed.
