Abstract: A door assembly is used for a refrigerator and a home appliance. The door assembly includes a door body, and a lighting panel coupled to a front surface of the door body. The lighting panel includes a panel frame with a coupling space, and a lighting device is installed to the panel frame. A light guide panel is arranged in the coupling space. A front panel is arranged on a front surface of the lighting panel in parallel to the light guide panel. A diffusion panel is arranged between the front panel and the light guide panel. Therefore, a user can change a color of a door surface by the lighting device without replacing a door panel, and the diffusion panel diffuses light once to make the light uniform.
