1. A rear plate covering a rear surface of an electronic device, the rear plate comprising:
a glass plate;
a first base plate attached to one surface of the glass plate;
a second base plate disposed so as to be spaced apart from the first base plate;
a first molding pattern layer disposed on one surface of the first base plate, including a plurality of first 3-dimensional (3D) patterns protruding toward the second base plate;
a first adhesive layer disposed between the first molding pattern layer and an opposite surface of the second base plate, wherein an index of refraction of the first adhesive layer is different from an index of refraction of the first molding pattern layer, such that at least a portion of light input through the first molding pattern layer is reflected on an interface with the first molding pattern layer; and
a shielding printing layer disposed on one surface of the second base plate.
