In this case, the distal end of the fifth part175may be spaced apart from the distal end of the second part172by a certain distance h in a direction intersecting the length direction of the bending part170II.

For example, the base170I may be coupled to the first recessed part160a. In this case, the distal end of the fifth part175may be spaced downward from the distal end of the second part172by a certain gap h. For example, the base170I may be coupled to the fourth recessed part. In this case, the distal end of the fifth part175may be spaced upward from the distal end of the second part172by a certain gap h.

For example, the base170I may be coupled to the second recessed part160b. In this case, the distal end of the fifth part175may be spaced apart from the distal end of the second part172to the right by a certain gap h. For example, the base170I may be coupled to the third recessed part160c. In this case, the distal end of the fifth part175may be spaced apart from the distal end of the second part172to the left by a certain gap h.

Accordingly, the inner surfaces of a part of the first part171, the second part172, the third part173, the fourth part174, and the fifth part175may define the boundary of the space170S. In addition, as one end and the other end of the bending part170II are fixed to the base170I, external force or stress applied to the bending part170II may be distributed to the bending part170II and the base170I.

A seventh part177and an eighth part178are located in a rear of the first part171, and may be adjacent to each other. The seventh part177and the eighth part178may contact the first part171. In addition, the coupling hole170cand the first guide hole170amay be formed to penetrate the seventh part177, the first part171, and the sixth part176. In addition, the coupling hole170cand the second guide hole170bmay be formed to penetrate the eighth part178, the first part171, and the sixth part176. Meanwhile, the seventh part177and the eighth part178may be referred to as a third base.

For example, the seventh part177may extend from one end of the first part171in the length direction of the first part171and then be folded toward the rear surface of the first part171. The seventh part177may include a first-first hole177aand a first-second hole177bformed to penetrate the seventh part177in the front-rear direction. The first-first hole177amay form a part of the first guide hole170a, and the first-second hole177bmay form a part of the coupling hole170c.

For example, the eighth part178may extend from the other end of the first part171in the length direction of the first part171and then be folded toward the rear surface of the first part171. The eighth part178may include a second-first hole178aand a second-second hole178bformed to penetrate the eighth part178in the forward-rearward direction. The second-first hole178amay form a part of the second guide hole170b, and the second-second hole178bmay form a part of the coupling hole170c.

In this case, the seventh part177and the eighth part178may constitute the base170I together with the first part171and the sixth part176. That is, the thickness t of the base170I may be the sum of the thickness t1of the first part171, the thickness t2of the sixth part176, and the thickness t3of the seventh part177. Here, the thickness t3of the seventh part177may be the same as the thickness of the eighth part178. Accordingly, torsional rigidity and/or bending rigidity of the base170I may be improved.

Referring toFIGS.9and10, the holder170may be coupled to the frame130at the rear of the frame130. Here,FIG.10is a cross section taken along line X-X′ ofFIG.9. The holder170may be located at the rear of the recessed part160, and may be detachably coupled to the recessed part160.

The first protrusion163amay be inserted into the first guide hole170a(seeFIG.7), and the second protrusion163bmay be inserted into the second guide hole170b(seeFIG.7). In this case, the first protrusion163amay protrude from the rear surface of the body161by a certain length tp. Here, the certain length tp is the same as the protruding length of the second protrusion163bfrom the rear surface of the body161, and may be greater than the thickness t of the base170I. Thus, the first protrusion163aand the second protrusion163bcan stably support the holder170into which they are inserted.

Further, when the first protrusion163aand the second protrusion163bare inserted into the first guide hole170aand the second guide hole170b, the coupling hole170c(seeFIG.7) may be aligned in the hole162(seeFIG.6). Accordingly, the first protrusion163aand the second protrusion163bmay guide the coupling of the holder170to the recessed part160.

Further, a fastening member F, such as a screw, may be inserted into the hole162through the coupling hole170cand screwed to the tapping part164(seeFIG.11). Thus, the holder170may be fixed to the recessed part160.

Meanwhile, the body161may include a first body161aextending obliquely or vertically with respect to the front surface of the frame130and a second body161bextending flatly with respect to the front surface of the frame130.

In this case, the sixth part176may be located in a rear of the second body161b, and may contact the second body161b. In addition, the fifth part175may be located in a rear of the first body161a, and may be spaced apart from the first body161aby a certain gap (gb). Accordingly, the second part172and the fifth part175may be elastically deformed toward the first body161aaccording to an external force, or may be return to an original position, that is, to a position where the fifth part175is spaced apart from the first body161aby a certain gap (gb) according to an elastic force.

Referring back toFIG.10, the guide panel117may form a side surface of the display device100. A rib117amay protrude toward the inner side of the display device100from the guide panel117. A foam pad110amay be coupled to the display panel110and the rib117aat between the display panel110and the rib117a. The optical sheet125and the diffusion plate129may face the foam pad110awith respect to the rib117a.

A portion forming the outer edge of the frame130may be inserted into the guide panel117. The frame130may be fixed to the guide panel117.

A rim (no reference numeral) of the reflective sheet126may contact the rear surface of the diffusion plate129, and the remaining portion of the reflective sheet126may obliquely extend in a rearward direction from the rim (see RF inFIG.10). In this case, the front surface of the second body161bmay be spaced apart from the front surface of the frame130in a rearward direction by a certain gap (ga). Accordingly, the fastening member F fastened to the tapping part164may not interfere with or contact the reflective sheet126.

Referring toFIGS.11and12, the back cover150may be located at the rear of the frame130, and may cover the rear of the frame130. Here,FIGS.11and12are a cross-section taken along the line Y-Y′ ofFIG.9. The back cover150may include a cover part151, a connection part152, and a coupling part153.

The connection part152may be bent from the cover part151, and may extend toward the frame130. An angle between the connection part152and the cover part151may be an obtuse angle. For example, the connection part152may extend parallel to the forward-rearward direction. The coupling part153may be curled from a distal end of the connection part152toward the inner surface of the connection part152. Meanwhile, the coupling part153may be referred to as a hanging part or a hook.

The back cover150may be detachably coupled to the holder170. Specifically, in the process of assembling the back cover150to the holder170by a user, the coupling part153may be guided to the third part173along the second part172. At this time, the force applied by a user is transmitted to the second part172through the coupling part153, so that the second part172and the fifth part175can be elastically deformed in a counterclockwise direction. Thus, the coupling part153may go over the second part172and be seated in or coupled to the third part173. At this time, the contact length between the coupling part153and the third part173may be L (seeFIG.7). In addition, the curvature of the coupling part153may be the same as that of the third part173.

Meanwhile, the frame130, the recessed part160, the holder170, the fastening member F, and the back cover150may include an electrically conductive material such as metal. Accordingly, Electro Magnetic Interference (EMI) noise of a plurality of electronic components installed in the frame130can be reduced. In addition, since the recessed part160and the holder170include a metal material, thermal deformation of these components can be minimized compared to a case in which a material such as plastic or synthetic resin is included.

Meanwhile, an insulating material (not shown) may be coated on the outer surface of the back cover150. In this case, the insulating material coated on the outer surface of the coupling part153may be removed while the coupling part153slides on the second part172and is seated on the third part173. Thus, electricity can be conducted from the recessed part160to the coupling part153through a portion of coupling part153where the coating of the insulating material is peeled off Thus, Electro Magnetic Interference (EMI) noise of a plurality of electronic components installed in the frame130can be reduced while insulating the outer surface of the back cover150.

Referring toFIG.13, the coupling part153of the back cover150may be curled while drawing a circle having a third radius r3with respect to a third center O3adjacent to the inner surface of the connection part152.

The back cover150may include a reinforcing part154. The reinforcing part154may extend toward the cover part151from the coupling part153. The reinforcing part154may face or be parallel to the inner surface of the connection part152. The reinforcing part154may be spaced apart from the inner surface of the connection part152by a first gap G1or may come into contact therewith. Accordingly, the rigidity of the back cover150against sagging and torsion may be improved.

Referring toFIG.14, the back cover150may include a rigid part155. The rigid portion155may be bent from the reinforcing part154. The rigid part155may form an obtuse angle with respect to the reinforcing part154, and may extend from the reinforcing part154toward the cover part151. The rigid part155may face or be parallel to the connection part152and/or cover part151. The rigid part155may be spaced apart from the inner surface of the cover part151by a second distance G2smaller than the first gap G1or may come into contact therewith. Accordingly, the rigidity of the back cover150against sagging and torsion may be further improved.

Referring toFIG.15, a rigid part155′ may be bent from the reinforcing part154. The rigid part155′ may extend in a direction intersecting the extension direction of the connection part152and/or the cover part151. The rigid part155′ may form an acute angle (theta2) with respect to the inner surface of the cover part151, and may extend from the reinforcing part154. The rigid part155′ may be adjacent to the inner surface of the cover part151. A portion where the reinforcing part154and the rigid part155′ are connected may be spaced apart from the inner surface of the cover part151by a second distance G2smaller than the first gap G1, or may come into contact therewith. Accordingly, the rigidity of the back cover150against sagging and torsion may be further improved.
