Abstract: The present invention relates to a multifunctional postbox having a light-emitting diode display unit that is capable of displaying various pieces of information by driving a light-emitting diode using power acquired from a solar cell module. More particularly, the present invention relates to a multifunctional postbox comprising: a solar cell module arranged at an outer surface of a main body of the postbox, which collects solar heat and generates an electrical energy; a battery arranged in an internal space of the postbox for storing the electrical energy generated by the solar cell module; and an address display panel arranged at an outer surface of the main body of the postbox, which displays address information by driving a light-emitting diode.
