A refrigerator, comprising: a main body that defines a freezing compartment and a refrigerating compartment, the freezing compartment and the refrigerating compartment being laterally arrayed in parallel; a first receiving part disposed in the freezing compartment and the refrigerating compartment; a first light emitting part configured to emit light to the first receiving part and including a light emitting diode; a sub door being rotatably connected to the front portions of the refrigerating compartment, the sub door including a frame being tetragonal in which a second receiving part is mounted; a second light emitting part configured to emit light to the sub-door and including a light emitting diode; compartment doors rotatably disposed on the front of the main body to selectively close the freezing compartment and the refrigerating compartment, said compartment doors including a freezing compartment door and a refrigerating compartment door; wherein the refrigerating compartment door includes: an outer door part defining an exterior of the refrigerating compartment door; an inner door part spaced rearward from the outer door part; and a door body coupling the outer door part and the inner door part to each other, wherein the outer door part includes: a glass member formed of a transparent material; a lamination treated layer formed on the glass member, the lamination treated layer being of a predetermined color to screen the transparent glass member and a predetermined pattern being formed on the glass member; a screening layer formed on a border of a rear surface of the glass member to prevent an emission of light from the first and second light emitting parts (17, 87) to an outside, and a viewing window which constitutes at least a portion of the front surface of the refrigerating compartment door, wherein the door body includes an insulation space, and a front portion of the insulation space is covered by the outer door part and a rear portion of the insulation space is covered by the inner door part, wherein a light emitted from the first and second light emitting parts (17, 87) is transmitted by the inner door part and the outer door part which are formed of transparent materials, and a portion of the light emitted from the first and second light emitting parts (17,87) is transmitted by the viewing window and the items stored in the first receiving part and the sub-door can be perceived from the outside. a main body that defines a freezing compartment and a refrigerating compartment, the freezing compartment and the refrigerating compartment being laterally arrayed in parallel;
