The fourth part (174) can be caught on the side wall (130S).

[0075] Accordingly, the holder (170) can be detachably coupled to the mounting portion (160). The first part (171) of the holder (170) before being coupled to the mounting portion (160) can be inclined with respect to a vertical plane (i.e., a plane parallel to the rear surface of the mounting portion (160) (see angle (theta t) of FIG. 8). First, the fourth part (174) of the holder (170) can be hung on the side wall (130S), and the protrusion (175) can be inserted into the hole (161h) using the tension of the first part (171). At this time, the first part (171) mounted on the mounting portion (160) can be elastically deformed to be parallel to the rear surface of the mounting portion (160). The coupling between the holder (170) and the mounting portion (160) can be strengthened by the elastic force of the holder (170).

[0076]

[0077] Referring to FIG. 12, the guide panel (117) may include a cover portion (1171) and a support portion (1172).

[0078] The cover portion (1171) may extend along the side wall (130S) of the frame (130) and form the outer surface of the frame (130). The cover portion (1171) may cover the side surface of the side wall (130S). In addition, the cover portion (1171) may cover the edge of the display panel (110). The cover portion (1171) may be referred to as a side part (117a) or a horizontal part (117a).

[0079] The support portion (1172) may intersect the cover portion (1171). The support portion (1172) may extend from the cover portion (1171) between the display panel (110) and the optical sheet (125). For example, the support portion (1172) may protrude from the inner surface of the cover portion (1171). For example, the support portion (1172) may protrude from the front end of the cover portion (1171) and may be bent at least twice. At this time, a gap (117g) may be formed between the cover portion (1171) and the support portion (1172). The support portion (1172) may be referred to as an inner part (117b) or a vertical part (117b).

[0080] The front pad (FP) may be positioned between the display panel (110) and the support (1172), and may be coupled or attached to the display panel (110) and the support (1172). The rear pad (RP) may be positioned between the support (1172) and the optical sheet (125), and may be coupled or attached to the support (1172) and the optical sheet (125).

[0081] The diffuser plate (129) may be adjacent to or in contact with the rear surface of the optical sheet (125) and may be positioned on the support portion (130R) of the frame (130). The substrate (122) may be coupled to the flat portion (130P) of the frame (130), and the optical assembly (124) mounted on the front surface of the substrate (122) may provide light to the display panel (110) through the diffuser plate (129) and the optical sheet (125) (see FIG. 3).

[0082] The protrusion (1173) may protrude from the inner surface of the cover portion (1171). The protrusion (1173) may be referred to as a latch protrusion (117c), a hook (117c), or a rib (117c). The protrusion (1173) may be caught on a portion of the third part (173) forming the boundary of the hole (176) and / or the rear surface of the support portion (130R) exposed through the hole (176). Accordingly, the guide panel (117) may be detachably coupled to the frame (130).

[0083]

[0084] Referring to FIGS. 13 and 14, the back cover (150) may be positioned at the rear of the frame (130). The back cover (150) may include a central portion (151), a connecting portion (152), and a joining portion (153). The central portion (151) may be formed flat or inclined. The connecting portion (152) may be bent forward from the edge of the central portion (151). The connecting portion (152) may be positioned at the rear of the protrusion (1173) below the cover portion (1171). The joining portion (153) may be curled from the end of the connecting portion (152) toward the inner surface of the connecting portion (152). The joining portion (153) may be curved to correspond to the groove (172g). The joining portion (153) may be referred to as a curling portion (153) or a hooking portion (153).

[0085] The user can push the back cover (150) forward toward the frame (130) while contacting the coupling portion (153) with the upper portion (171T) of the first part (171) of the holder (170) (see arrow (AW) in Fig. 13). As a result, the upper portion (171T) can be elastically deformed toward the second part (162) of the mounting portion (160), and the coupling portion (153) can move beyond the upper portion (171T) toward the second part (172) of the holder (170). The coupling portion (153) mounted on the groove (172g) of the second part (172) can be caught by the upper portion (171T) that has been restored to its original position.

[0086] Accordingly, the back cover (150) can be detachably coupled to the holder (170). The frame (130), side frame (117), and back cover (150) can be coupled to each other without a separate fastening member such as a screw.

[0087] A plurality of anchoring portions (160) and a plurality of holders (170) may be arranged along the periphery of the frame (130). For example, a plurality of first anchoring portions (160a) and a plurality of first holders (170a) may be spaced apart from each other along the upper side (130U) of the frame (130). For example, a plurality of second anchoring portions (160b) and a plurality of second holders (170b) may be spaced apart from each other along the left side (130L) of the frame (130). For example, a plurality of third anchoring portions (160c) and a plurality of third holders (170c) may be spaced apart from each other along the right side (130R) of the frame (130).

[0088] Each of the plurality of protrusions (1173) can be coupled to each of the plurality of holders (170). The frame (130) and the side frame (117) can be coupled to each other at positions corresponding to the plurality of holders (170), and the back cover (150) can be caught on the plurality of holders (170). Accordingly, since the frame (130), the side frame (117), and the back cover (150) are coupled to each other at positions that are the same or corresponding to each other, the degree of freedom in utilization of space other than their coupling positions and design can be increased.

[0089] The upper position of the back cover (150) may be higher than the upper position of the frame (130). That is, the upper surface of the connecting portion (152) of the back cover (150) may be positioned a certain distance (Ha) above the upper surface of the side wall (130S) of the frame (130). Accordingly, the frame (130) may be minimized from being exposed to the outside through the gap between the connecting portion (152) and the cover portion (1171).

[0090] A gap (Ga) may be formed between the upper end of the frame (130) and the inner surface of the side frame (117). That is, the gap (Ga) may be formed between the upper surface of the side wall (130S) of the frame (130) and the lower surface of the cover portion (1171). The gap (Ga) may be equal to or greater than the thickness of the third part (173). Accordingly, contact between the frame (130) and the side frame (117) may be minimized, and wear of the side frame (117) by the frame (130) may be minimized.

[0091] The frame (130), the mounting portion (160), the holder (170), and the back cover (150) may include an electrically conductive material such as metal. The EMI (Electro Magnetic Interference) noise of the plurality of electronic components mounted on the frame (130) can be reduced. In addition, since the frame (130), the mounting portion (160), the holder (170), and the back cover (150) include a metal material, thermal deformation of these components can be minimized compared to cases where they include materials such as plastic or synthetic resin. An insulating material can be coated on the surface of the back cover (150). The insulating material can be removed during the process in which the coupling portion (153) slides on the upper portion (171T) and is installed on the second part (172). Electricity can flow through the frame (130) and the holder (170) to the portion of the coupling portion (153) where the coating of the insulating material is removed. In this way, the EMI noise of multiple electronic components mounted on the frame (130) can be reduced while insulating the surface of the back cover (150).
