A mobile terminal, comprising:

• a terminal body having a front surface and a rear surface;
• a transmissive region formed on at least one of the front surface and the rear surface;
• an image module mounted in the terminal body;
• and
• an optical source configured to transmit light towards the image module, wherein the image module includes:
• a base member including a light transmissive material;
• a first layer having a first protruding pattern protruding from a first surface of the base member, wherein the first protruding pattern is visually exposed to an outside;
• a second layer including an opaque material and covering a second surface of the base member, wherein the first and second surfaces of the base member are on opposite sides of the base member;
• one or more image through-holes in the second layer and configured to pass light from a light source through the one or more image through-holes to the protruding pattern to illuminate and present one or more images with the first protruding pattern;
• and
• a third layer disposed on the second layer, wherein at least a portion of the third layer overlaps the one or more image through-holes, wherein the at least the portion of the third layer is exposed toward the first layer through the one or more image through-holes and the base member, wherein the second layer is exposed toward the first layer through the base member, and
• wherein the one or more images are formed by a combination of the first layer, the second layer and the third layer.
