4 and 5, the electromagnetic wave shielding layer 112 provided in the electronic device according to an embodiment of the present invention may be formed of a mesh layer 1121 formed of an electromagnetic wave shielding material.

As for the mesh layer 1121, any one of nickel, copper, gold, silver, iron, and cobalt has a mesh structure as shown in a) of FIG. 4, or as shown in b) of FIG. 4, gold / copper and silver / Combinations of copper, copper / nickel, iron / nickel, copper / nickel / cobalt and the like can be made into a mesh structure. In this case, conductive metals such as copper, gold, and silver block electromagnetic waves caused by electric fields generated inside electronic devices, and magnetic materials such as nickel, iron, and cobalt prevent electromagnetic waves caused by magnetic fields generated inside electronic devices. Block it. Therefore, most preferably, the mesh layer is formed by combining the conductive metal and the magnetic material.

In addition, as shown in FIG. 4, the mesh layer 1121 may have a gap or a hole 1121a due to the characteristics of the network structure, and visible light may pass through the gap or the hole 1121a. In addition, it can transmit visible light and block electromagnetic waves.

As shown in b) may be formed of a metal layer 1123 made of an electromagnetic shielding material.

In this case, the rubber layer 1122 has a thickness of 0.01 mm to 5.0 mm and is formed by dispersing a large amount of electromagnetic wave shielding material 1122 a in a rubber material.

Can fall. That is, since the visible light is diffracted even in the slits at very narrow intervals, the visible light is sufficient if the visible light is larger than the size enough to cause the diffraction to be transmitted to the outside of the electronic device.

The light emitting device 114 is installed in the body 111 to be electrically connected to the circuit board 113. The light emitting element 114 is preferably made of an LED (LED) element, it is possible to emit light of any one of white, blue, green or red, or a combination of two or more.

As such, when one or more colors are emitted, different colors are emitted according to various states of the electronic device, so that the user can recognize the state of the electronic device. For example, the user may emit light by configuring the normal standby state of the electronic device to emit white light, the normal operating state to green, the abnormal standby state to blue, the abnormal operation state, or an abnormal state of a component such as a short circuit in various circuits. The state of the electronic device can be distinguished from the color of the element 114.

Since only the electromagnetic wave needs to be blocked, visible light generated from the light emitting element 114 may be emitted to the outside of the electronic device even though the transmission hole is not formed.

In addition, as described above, when the electromagnetic wave shielding layer 112 is formed of a rubber layer 1122 in which a conductive material is dispersed, a metal layer 1123 made of a conductive material, or a mesh layer 1121 made of a conductive material, Since the conductive function may be performed, the light emitting device 114 may be electrically connected to the light emitting device 114 to supply power to the light emitting device 114.

Since the visible light generated from the light emitting element 114 formed inside the electromagnetic wave shielding layer 112 is formed through the gaps, holes 1121a or through holes 1122b and 1123b, the electromagnetic wave shielding layer 112 It can be diverted to the outside.

Visible light emitted to the outside of the electromagnetic wave shielding layer 112 is emitted to the outside of the electronic device through the body 111 formed of a transparent material that can be recognized by the user.
