For example, the first circuit board 104a may constitute a backlight driver 183 for controlling the backlight unit 184. The first circuit board 104a constituting the backlight driver 183 may control the plurality of light sources to be turned on / off or scanning driven.

As described above, the support member 102 is provided inside the cover bottom 101 supporting the display module 180 to provide a space 103a on which the first circuit board 104a can be seated. In addition, the back surface of the accommodating portion 101b (in this figure, the back surface of the second accommodating portion 101d) constitutes a part of the rear appearance of the image display apparatus 100. According to the above structure, the existing back cover, which has been coupled to the rear surface of the cover bottom 101 to cover the first circuit board 104a, becomes unnecessary. Therefore, the back cover can be removed to obtain effects such as material cost reduction and weight reduction.

The second circuit board 104b may be mounted in the accommodation groove 102b formed on the front surface of the support member 102. The second circuit board 104b may be a timing controller 182a that controls driving of the panel 181 of the display module 180. The second circuit board 104b is disposed between the display module 180 and the support member 102, and thus heat generated in the second circuit board 104b is difficult to be discharged to the outside due to its structure.

In order to improve heat dissipation characteristics of the second circuit board 104b, the second circuit board 104b may be configured to be in direct or indirect contact with the cover bottom 101 formed of a metal material. For example, referring to the drawing, the cover bottom 101 is in contact with the second circuit board 140b via the intermediate member 105 passing through the hole 102c of the support member 102, thereby providing a second circuit. The heat generated in the substrate 104b is configured to be discharged to the outside. According to the above structure, the heat generated from the second circuit board 104b is transferred to the cover bottom 101 made of a metal having excellent thermal conductivity and is discharged to the outside.

The rear deco 106 may be coupled to the cover bottom 101 to form another part of the rear exterior of the image display device 100.

According to the above structure by the cover bottom 101 and the rear deco 106, a new rear design different from the rear design implemented by the existing back cover can be implemented.

The rear deco 106 may be firmly fixed to the cover bottom 101 by a locking structure. In this embodiment, the locking structure using the clip 107 is illustrated. Specifically, the cover bottom 101 is coupled to the clip 107 having a locking portion 107a. The rear deco 106 has a projection 106a and a hook portion 106b, and the hook portion 106b is caught by the locking portion 107a after the protrusion 106a is inserted into the locking groove 101e of the cover. The rear decor 106 is configured to couple to the cover bottom 101.

The locking portion 107a may include first and second locking grooves 107b and 107c provided at each end of the clip 107 to protrude in opposite directions. This drawing illustrates that the first and second locking grooves 107b and 107c protrude to face each other. According to this structure, even if the rear deco 106 receives the force in one direction and the hook portion 106b with respect to any one of the locking grooves 107b and 107c is released, the other one of the locking grooves 107b and 107c is released. Engagement of the hook portion 106b with respect may be made stronger. Thus, a better clamping force can be provided.

The fastening structure of the rear deco 106 is not limited only to the locking structure. The rear deco 106 may be fixed to another structure using a screw, adhesive member, etc., such a structure may be applied with the locking structure described above.

An electronic device may be mounted in the space 103b between the cover bottom 101 and the rear decor 106. For example, a third circuit board 104a formed to generate a control signal related to driving the panel 181 of the display module 180 may be mounted on the rear surface of the cover bottom 101.

The middle cabinet 108 is disposed to cover a portion of the clip 107 and forms a side appearance of the image display device 100. In this figure, it is shown that the middle cabinet 108 is arrange | positioned so that the clip 107 mounted in the back surface of the mounting part 101a may be covered. A portion of the clip 107 may be secured between the middle cabinet 108 and the cover bottom 101 by passing through the through hole of the middle cabinet 108, and the middle cabinet 108 and the clip 107 may be screwed. It may be fastened to the cover bottom 101 by).

The middle cabinet 108, the rear decor 106, and the cover bottom 101 may form a continuous outer surface extending from the side of the image display device 100 to the rear surface. In this case, the rear deco 106 may be formed to have a curved portion so that the side and the rear may be smoothly connected without being angled to each other. In addition, the end of the rear deco 106 may be inserted and fixed in the gap 103c between the middle cabinet 108 and the clip 107. The structure enhances the fastening force of the rear decor 106.

A guide panel 109a supporting the panel 181 of the display module 180 may be coupled to the cover bottom 101. In this drawing, the guide panel 109a is coupled to cover the outer surface of the cover bottom 101. The top case 109b may be disposed between the guide panel 109a and the middle cabinet 108 to cover the front end of the panel 181.
