[ A light emitting diode (LED) 43 mounted on the light emitting diode 43 and a lens 45 having a circular shape for diffusing light generated in the light emitting diode 43.

The printed circuit board 41 is elongated so as to have a length in one direction corresponding to the display panel 10, and a plurality of printed circuit boards 41 are disposed in parallel to each other.

A connection board 47 connecting one ends of the printed circuit boards 41 is disposed at one end of the printed circuit boards 41 so that the printed circuit boards 41 can be operated in cooperation with each other via the connection board 47 Respectively.

A plurality of light emitting diodes 43 are provided and are spaced apart from each other in the longitudinal direction of the printed circuit board 41. A plurality of lenses 45 are provided to each of the plurality of light emitting diodes 43. [

Although not shown, a metal layer (not shown) formed of a metal having excellent heat transfer performance such as copper for heat dissipation may be formed on the front surface of the printed circuit board 41 on which the light emitting diode 43 is mounted.

Between the display panel 10 and the backlight unit 40, optical sheets 70 for improving the optical characteristics of light emitted from the backlight unit 40 to the display panel 10 are disposed.

The optical sheets 70 include a diffusion sheet 71 for diffusing light emitted from the backlight unit 40 to improve luminance uniformity and a diffusion sheet 71 for diffusing light diffused by the diffusion sheet 71 in a direction perpendicular to the display panel 10 And a light collecting sheet 73 for aligning the light direction so as to be incident thereon.

The bottom chassis 50 is formed in a rectangular shape and disposed at a lower portion of the backlight unit 40, and is provided to receive the display panel 10.

The bottom chassis 50 includes a bottom portion 51 on which the backlight unit 40 is placed and an extension portion 53 extending upward from the periphery of the bottom portion 51. The bottom chassis 51 is formed of a thermally conductive metal material, And dissipates the heat transferred from the diode 43.

The bottom chassis 50 has a shape corresponding to that of the printed circuit boards 41 and a plurality of seating grooves 51a on which the printed circuit boards 41 are mounted are recessed.

A connecting board seating groove 51b having a shape corresponding to that of the connecting board 47 is recessed at one side of the plurality of seating grooves 51a.

The printed circuit boards 41 and the connecting board 47 are seated and supported on the bottom chassis 50 through the seating grooves 51a and the connecting board seating grooves 51b without any additional parts.

The rear cover 60 is disposed on the rear surface of the bottom chassis 50 to form a rear appearance.

3 to 5, an external radio wave receiving module 80 is disposed between the bottom chassis 50 and the rear cover 60. The external radio wave receiving module 80 receives radio waves from the outside, (81), Bluetooth (83), and the like.

Since the WiFi 81 and the Bluetooth 83 receive the radio wave from the outside, the reception ratio can be improved by being disposed on the front surface of the display panel 10.

The wifi 81 and the Bluetooth 83 are disposed on the front surface of the display panel 10 so that the bezel 31 of the top chassis 30, which surrounds the front edge of the display panel 10, The WiFi 81 and the Bluetooth 83 should be located between the mobile terminal 10 and the base station.

However, since the bezel portion 31 is provided as a narrow bezel having a small thickness, if the space is narrow and the WiFi 81 and the Bluetooth 83 are disposed, the WiFi 81 and the Bluetooth 83 are exposed to the outside.

The wifi 81 and the Bluetooth 83 are fixed to the rear surface of the bottom chassis 50 disposed on the rear surface of the display panel 10 and the wifi 81 and the Bluetooth 83 are attached to the rear surface of the display panel 10 The reception ratio for receiving the external radio wave is inevitably lowered due to the bottom chassis 50, which is a metallic material disposed on the front surfaces of the Wi-Fi 81 and the Bluetooth 83. [

In order to maximally improve the reception ratio of the Wi-Fi 81 and the Bluetooth 83, it is necessary to dispose the Wi-Fi 81 and the Bluetooth 83 on the outer side of the bottom chassis 50,

The antenna unit 90 is disposed on the front surface of the display panel 10 so as to improve the reception ratio of the external radio waves while the WiFi 81 and the Bluetooth 83 are disposed on the rear surface of the bottom chassis 50, And the Bluetooth 83 are connected to the antenna unit 90 by the wire W. [

The antenna unit 90 is provided in a number corresponding to the number of the Wi-Fi 81 and the Bluetooth 83 and is connected to the Wi-Fi 81 and the Bluetooth 83, respectively.

The antenna unit 90 is fixed to the bezel 31 of the top chassis 30 so that the antenna unit 90 is disposed on the front surface of the display panel 10.

The antenna unit 90 fixed to the bezel unit 31 is thinner than the bezel unit 31 to prevent exposure to the outside and has a shape corresponding to the shape of the bezel unit 31.

The antenna 90 is fixed to the bezel 31 at a position above the top chassis 30. The WiFi 81 and the Bluetooth 83 connected to the antenna 90 by the wire W are connected to the antenna 90, The length of the wire W connecting the WiFi unit 81 and the Bluetooth unit 83 to the antenna unit 90 is made as short as possible so as to be located at the top of the bottom chassis 50 so as to correspond to the position of the antenna unit 90.

6, it is preferable that the antenna unit 90 is disposed on the left and right outer sides of the upper portion of the top chassis 30 in order to maximize the reception ratio of the external radio waves. However, as shown in FIG. 7, (90) may be disposed other than the right and left outer sides of the upper portion of the top chassis (30).

6, when the antenna portion 90 is disposed on the left and right outer sides of the upper portion of the top chassis 30, the shape of the antenna portion 90 corresponds to the bezel portion 31, The shape of the antenna portion 90 is not limited to the shape of the bezel portion 31 when the antenna portion 90 is disposed at a position other than the left and right outer edges of the upper portion of the top chassis 30 as shown in FIG. It may be provided so as to have a straight shape so as to correspond thereto.

Since the WiFi 81 and the Bluetooth 83 connected to the antenna unit 90 must be spaced apart from each other by a predetermined distance when the antenna unit 90 is disposed at a position other than the left and right outer sides of the top chassis 30, 81 and the Bluetooth 83 are spaced apart from each other by a predetermined distance and the antenna unit 90 is disposed at a position corresponding to the WiFi 81 and the Bluetooth 83. [

The antenna unit 90 is disposed on the front surface of the display panel 10 and the antenna unit 90 is connected to the wifi 81 and the Bluetooth 83 disposed on the rear surface of the bottom chassis 50 by the wire W Even if the WiFi 81 and the Bluetooth 83 are disposed behind the display panel 10, the antenna unit 90 disposed in front of the display panel 10 receives the external radio waves and transmits the WiFi 81 and the Bluetooth 83 83, it is possible to improve the reception ratio of the external radio waves.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the scope of the present invention. .
