Abstract: Provided is a mobile terminal. The mobile terminal includes a window, a display disposed on a rear surface of the window to output an image, a terminal body having a front surface on which the window is disposed, and an external cover coupled to an outer surface of the terminal body to protect an outer appearance of the terminal body. The external cover comprises a front cover that covers at least one outer surface of top, bottom, left, and right surfaces of the terminal body and a portion of a front surface of the window. Since the external cover covers a portion of a front surface of the mobile terminal in addition to an outer surface of the mobile terminal, an area for protecting the mobile terminal against an external impact or foreign substances may increase.
