3 and 4, a circuit board 180 is disposed inside the terminal body. The circuit board 180 may be mounted to the rear case 102 as shown or may be installed in a separate internal structure. The circuit board 180 may be configured as an example of a control unit for operating various functions of the mobile terminal 100. The first sound output unit 160 and the first camera unit 121 may be mounted on the circuit board 180 as shown in FIG.

The display unit 150 displaying information processed by the mobile terminal 100 is disposed on one surface of the terminal body. The display unit 150 may be disposed to occupy most of the front surface of the terminal body. The display unit 150 includes a display 151 and a window 152 covering the display 151.

The mobile terminal 100 has a frame for receiving the display 151. In this embodiment, it is shown that the frame is formed of the front case 101 forming the outer appearance of the terminal body.

The window 152 is divided into a central region C corresponding to the display 151 and an edge region S surrounding the central region C. The edge area S may be seated and supported by the seating part 101a, and color processing may be performed on the edge area S to distinguish it from the center area C.

In addition, a groove 160b may be formed on a side surface of the window 152 disposed to face the side wall of the front case 101 to form an assembly gap. According to the above structure, since the sound generated from the first sound output unit 160 is emitted along the assembly gap between the front case 101 and the window 152, a hole formed independently for the sound output is not visible, so it moves. The appearance of the terminal 100 may be simpler.

The display 151 is disposed on the rear surface of the window 152 and is accommodated in the front case 101 to form the display unit 150 together with the window 152.

The gradation unit 152a may be formed by being directly printed on the rear surface of the window 152 through a process such as silk screen printing or pad printing, or a separate film processed by gradation may cover the window 152.

In this figure, the gradation portion 152a is directly printed on the rear surface of the window 152 and gradually formed brightly toward the three-dimensional film 154. For reference, in FIG. 4, the gradation part 152a has a predetermined thickness and the thickness becomes thinner as it approaches the three-dimensional film 154. However, this is for convenience of understanding (the display and the gradation part of the gradation part 152a) 152a) is shown conceptually for showing that the closer to the three-dimensional film 154, the brighter.

At least a portion of the gradation part 152a is disposed to overlap with the three-dimensional film 154. According to the above structure, since the gradation part 152a formed to gradually change the contrast is formed to cover the ends of the three-dimensional film 154, there is a sense of heterogeneity that may occur in the stepped portions of the window 152 and the three-dimensional film 154. This may be minimized, and a mobile terminal 100 in which icons, logos, specific patterns, and the like having a more advanced feeling may be implemented.
