For example, the support member750may have the same shape as the first guide rail721and the second guide rail723.

The third side body714and the support member750may be fixed to each other by a coupling structure of a convex portion and a concave portion. The third side body714and the support member750may be fixed to each other by a first coupling structure and a second coupling structure for limiting movement in multiple directions.

For another example, although not shown, a locking groove625extending along the left and right directions may be provided on the upper surface of the top plate610, and the buffer member620may be fitted into the locking groove625.

As the buffer member620fills the space between the top plate610and the display panel100to which the case member is coupled. Therefore, it is possible to prevent a gap from being formed between the frame300and the top plate610due to the sagging of the central portion of the top plate610by the load of the display panel100and the case member.

FIGS.20and21are diagrams illustrating a heat dissipation structure according to an embodiment of the present disclosure.

Referring toFIGS.20and21, the display device may further include a heat dissipation mechanism for dissipating heat generated from components accommodated in the box800to the outside.

The box800may include an air inlet871serving as a path through which the air is introduced, and an air outlet873serving as a path through which the air is discharged. The air inlet871may include inlet slits871aopened rearward. The air outlet873may include outlet slits873aopened rearward. The inlet slits871amay be positioned adjacent to one side (e.g. right side) of the box800, the outlet slits873amay be positioned adjacent to the other side (e.g. left side) of the box800.

The heat dissipation mechanism may include one or more fans880. The fan880may be disposed adjacent to the outlet slits873aof the air outlet873in the box800. The fan880may form a difference between an internal air pressure and an external air pressure. As the external air pressure is increased by the fan880compared to the internal air pressure, the external air may be introduced into the box800through the air inlet871. The air introduced through the air inlet871may be discharged to the outside of the box800by the fan880after cooling the components accommodated in the box800.

A plurality of fans880may be configured. For example, the fan880may include a first fan881and a second fan883disposed closer to the outlet slits873aof the air outlet873than the first fan881.

Air vents881aand883aof the first fan881and the second fan883may have a predetermined discharge direction. A discharge direction of the fan880may correspond to a direction in which the air vents881aand883aare opened.

For example, the discharge direction of the second fan883may be directed toward the outlet slits873a.The discharge direction of the first fan881may be directed toward a direction tilted by the predetermined angle from the discharge direction of the second fan883. Here, the predetermined angle may be an acute angle or a right angle. The discharge direction of the first fan881may be directed toward the other side (e.g. a left side) of the box800. If necessary, in consideration of the selected orientational direction, a duct for guiding the air flow path may be further provided.

FIGS.22to24are diagrams illustrating a sound reflector according to an embodiment of the present disclosure.

Referring to22to24, the display device may further include a sound reflector950. The sound reflector950controls a sound path of sound provided from the speaker420. That is, the sound reflector950switches a path of sound provided from the speaker420and may control the path so that the sound is directed to the front where a user is located. Accordingly, the display device according to an exemplary embodiment of the present disclosure has an advantage of minimizing sound loss and providing high quality sound to the user.

The sound reflector950may be positioned on the lower surface of the top plate610. Sound generated by the speaker420disposed on the rear surface of the PCB plate400may be provided to the front by changing a path by the sound reflector950disposed on the lower surface of the top plate610. To reduce sound loss, the top plate610may include a sound hole617. The sound hole617may overlap with the speaker420in the up-down direction. The sound hole617may overlap with the sound reflector950in the up-down direction.

The sound reflector950may include a fixing part951and an inclined part953.

The fixing part951may be a part fixed to the lower surface of the top plate610. The fixing part951may be detachably coupled to the top plate610. For example, as a fixing mechanism for fixing the fixing part951and the top plate610, a magnet910and an auxiliary plate920detachably provided to the magnet910may be further included. The auxiliary plate920may be a ferromagnetic substance. The magnet910may be fixed to an upper surface of the fixing part951through at least one fixing member. The auxiliary plate920may be fixed to the lower surface of the top plate610through at least one fixing member. The fixing member may be a screw, but is not limited thereto.

The inclined part953extends from the fixing part951and may have a shape inclined with respect to the fixing part951by a predetermined angle. As the inclined part953has a predetermined inclination, a distance between the inclined part953and the top plate610may gradually increase from the rear to the front. The inclined part953may overlap with the sound hole617in the vertical direction. That is, the sound hole617exposes the inclined part953positioned below the top plate610, but may be opened toward the speaker420. Accordingly, the sound provided from the speaker420may be transmitted to the user located in the front after the path is changed in the inclined part953through the sound hole617.
