The display unit includes a flexible circuit board connected to transmit and receive signals to and from the display unit and the main circuit board, and a connector for connecting the flexible circuit board to the main circuit board.

As an example related to the present invention, the mobile terminal includes a contact electrically connected to the connector and formed on the main circuit board.

According to an embodiment of the present invention, the mobile terminal includes an antenna unit formed at an end of the terminal body for transmitting and receiving a wireless communication signal, and the contact unit may include: And is disposed apart from the antenna portion.

In one embodiment of the present invention, the support member includes at least one support protrusion protruding from the support member and configured to support the battery.

In one embodiment of the present invention, the support protrusion is formed of an elastic material so as to elastically support the battery from the support member.

As an example related to the present invention, the portable terminal further includes a main circuit board disposed inside the terminal body and electrically connected to the battery. The battery includes a connection portion protruded to be electrically connected to the main circuit board. The supporting member is formed to cover at least a part of the main circuit board and includes a battery compartment accommodated in the battery compartment corresponding to the battery from the one surface and a connection hole formed to penetrate the connection part .

According to an embodiment of the present invention, a surface of the battery compartment supporting the battery is bent to correspond to a curved surface of the battery.

In the present invention, a circuit board is formed in a space formed between an arc-shaped battery and a middle frame of a terminal body, and an internal space through which electronic components can be mounted is expanded.

In addition, the connecting element of the display unit is disposed to be spaced apart from the antenna unit inside the mobile terminal, thereby reducing the electromagnetic influence on the antenna unit.

Also, since the outer surface of the rear surface of the battery is curved to improve the grip feeling of the mobile terminal and the thickness of the side surface of the mobile terminal is reduced, the visual sense of quality is improved.

Electronic parts and the like can also be formed on a region of the main circuit board 282 overlapping with the battery 300, so that the contact portion 210c can be formed in a free position. Therefore, the contact portion 210c may be formed so as to form a distance from the antenna portion 226. [ Therefore, the influence of the contact portion 210c on the antenna portion 226 can be reduced. The area inside the mobile terminal where the antenna unit 226 can be formed can be increased.

Therefore, the performance of the antenna unit 226 built in the mobile terminal 200 can be improved.

According to an embodiment of the present invention, the main circuit board 282 can be extended to overlap with at least a part of the battery 300. [ Therefore, since the area where the electronic parts can be mounted is expanded, the size of the mobile terminal can be reduced.

In addition, since the rear surface of the mobile terminal is formed by a curved surface protruding only from the central portion, it is possible to arrange various electronic parts by utilizing the center portion and improve the visual quality that the side surface is thin. In addition, the grip feeling can be enhanced by the protruding curved surface.

In addition, the battery receiving space 206 is formed in substantially the same shape as the battery 300. That is, the supporting surface for supporting one side of the battery 300 in the storage space 206 may be formed as a curved surface having a curvature substantially equal to a curvature of the battery 300.

A connection hole 206 'is formed on one side of the battery receiving space 206. The connection portion 301 of the battery 300 is electrically connected to the main circuit board 282 through the connection hole 206 '.

The main circuit board 282 may include an area overlapping with the battery 300. Accordingly, the area of the main circuit board 282 on which the electronic component can be mounted is expanded, so that the internal space can be expanded.
