[0075] FIG. 10 is a cross-sectional view of a structure in which a frame, a back cover, and a side frame are combined according to one embodiment of the present disclosure, and FIG. 11 is a perspective view of a latch according to one embodiment of the present disclosure.

[0076] Referring to FIGS. 10 and 11, the latch (82) may include a body (822) that protrudes outward from the banding portion (812) of the frame (80) and a protrusion (821) that protrudes left-right or up-down from the body (822) so that one side of the display panel (10) extends. The latch (82) may have an overall hook shape when viewed from the up-down or left-right directions.

[0077] A first curved portion (R1) and a first inclined portion (S1) may be formed on the protrusion (821). The first curved portion (R1) and the first inclined portion (S1) may form a protruding end of the protrusion (821). The first curved portion (R1) may protrude convexly in a direction toward the display panel (10). For example, in a latch (82) protruding to the left, the direction toward the display panel (10) may be a direction between the left side and the front side (left front). For example, in a latch (82) protruding to the right, the direction toward the display panel (10) may be a direction between the right side and the front side (right front). For example, in a latch (82) protruding upward, the direction toward the display panel (10) may be a direction between the upper side and the front side. The first curved portion (R1) may extend in a direction intersecting the protruding direction. For example, the first curved portion (R1) may be extended in the vertical or left-right direction along one side of the display panel (10).

[0078] The first inclined portion (S1) may be connected to the first curved portion (R1). The first inclined portion (S1) may be an inclined surface that is inclined backward with respect to the left-right direction or the up-down direction in which one side of the display panel (10) extends. The first inclined portion (S1) may extend in the direction in which the first curved portion (R1) extends. For example, the first inclined portion (S1) may extend long in the up-down direction or the left-right direction in which one side of the display panel (10) extends.

[0079] The first inclined portion (S1) may include at least one inclined surface. For example, the first inclined portion (S1) may include a plurality of inclined surfaces, and the inclined angles of the inclined surfaces of the first inclined portion (S1) may decrease as they move farther rearward from the first curved portion (R1). For example, the inclined angle (Ag1, see FIG. 13) of a first inclined surface among the inclined surfaces of the first inclined portion (S1) that is connected to the first curved portion (R1) may be greater than the inclined angle (not shown) of a second inclined surface that is connected to the first inclined surface and faces the first curved portion (R1) with respect to the first inclined surface. That is, the inclined angle of the first inclined surface of the first inclined portion (S1) may be greater than the inclined angles of the remaining inclined surfaces of the first inclined portion (S1).

[0080] A second curved portion (R2) may be formed between the protrusion (821) and the body (822). The second curved portion (R2) may be connected to one side of the first curved portion (R1) and may be formed concavely in a direction opposite to the direction in which the first curved portion (R1) protrudes. The first curved portion (R1) and the second curved portion (R2) may form a continuous curve. The second curved portion (R2) may extend in the direction in which the first curved portion (R1) extends. For example, the second curved portion (R2) may extend in a vertical direction or a left-right direction in which one side of the display panel (10) extends.

[0081]

[0082] Fig. 12 is a perspective view of a fastening portion according to one embodiment of the present disclosure.

[0083] Referring to FIG. 12 together with FIG. 10, the fastening portion (94) may include a fastening body (941) protruding from the inner surface of the back cover (90), a fastening leg (942) having one end connected to the fastening body (941) and extending forward, and a catch (943) protruding from the other end of the fastening leg (942) toward the latch (82). The fastening portion (94) may have an overall hook shape when viewed from the top and bottom or left and right directions.

[0084] The fastening body (941) may include a plurality of plates that are spaced apart from each other and extend parallel to each other. Each plate may protrude forward from the inner surface of the back cover (90) and inwardly of the back cover (90). The fastening leg (942) may extend forwardly from one side of the front surface (9411) of the fastening body (941). The fastening leg (942) may be connected to the front surface (9411) of each plate forming the fastening body (941) and may be formed integrally with the fastening body (941). That is, the front surfaces (9411) of each plate of the fastening body (941) may be connected to each other by one end of the fastening leg (942). The catching protrusion (943) may be spaced forward from the fastening body (941) and may protrude in the left-right or downward direction along which one side of the display panel (10) extends from the fastening leg (942). A groove (G1) on which a latch (82) can be caught may be formed by the front surface (9411) of the fastening body (941), the inner surface (9421) of the fastening leg (942), and the rear surface of the catch (943). The groove (G1) may have a concave shape toward the side (93) of the back cover (90). The groove (G1) may be referred to as a groove.

[0085] A fourth curved portion (R4) and a second inclined portion (S2) may be formed on the catch (943). The fourth curved portion (R4) and the second inclined portion (S2) may form at least a portion of the protruding end of the catch (943). The fourth curved portion (R4) may protrude convexly in a direction opposite to the direction toward the display panel (10). For example, in the catch (943) protruding to the left from the fastening leg (942), the direction opposite to the direction toward the display panel (10) may be a direction toward between the left and rear sides (left rear). For example, in the catch (943) protruding to the right from the fastening leg (942), the direction opposite to the direction toward the display panel (10) may be a direction toward between the right and rear sides (right rear). For example, in the hook (943) protruding downward from the fastening leg (942), the direction opposite to the direction toward the display panel (10) may be the direction toward the lower side and the rear side. The fourth curved portion (R4) may extend in a direction intersecting the protruding direction. For example, the fourth curved portion (R4) may extend in a vertical direction or a left-right direction along which one side of the display panel (10) extends.

[0086] The second inclined portion (S2) may be a forward-slanted surface with respect to the left-right direction or the up-down direction in which one side of the display panel (10) extends. For example, the second inclined portion (S2) may be formed between the front surface (9431) and the inner surface (9432) of the catch (943). Alternatively, for example, the second inclined portion (S2) may be connected to the inner surface (9432) of the catch (943) and form the inclined front surface (9431) of the catch (943). The second inclined portion (S2) may extend in the direction in which the fourth curved portion (R4) extends. For example, the second inclined portion (S2) may extend long in the up-down direction or the left-right direction in which one side of the display panel (10) extends.

[0087] A third curved portion (R3) may be formed between the fastening leg (942) and the catch (943). The third curved portion (R3) may be connected to one side of the fourth curved portion (R4) and may be formed to be concave in a direction opposite to the protruding direction of the fourth curved portion (R4). The third curved portion (R3) and the fourth curved portion (R4) may form a continuous curve. At least a portion of the third curved portion (R3) and at least a portion of the fourth curved portion (R4) may form the rear surface of the catch (943). The third curved portion (R3) may extend in the direction in which the fourth curved portion (R4) extends. For example, the third curved portion (R3) may extend in a vertical direction or a left-right direction in which one side of the display panel (10) extends.

[0088]

[0089] Referring again to FIG. 10, the side frame (20) can extend along the perimeter of the display panel (10). For convenience, FIG. 10 shows a structure in which the fourth part (24) among the four parts (21, 22, 23, 24) constituting the side frame (20) is combined with the frame (80) and the back cover (90), but the first part (21) and the third part (23) among the four parts can also be combined with the frame (80) and the back cover (90) by the same structure.

[0090] The side frame (20) may include a horizontal portion (24H) that supports the rear surface of the display panel (10) and a vertical portion (24V) that extends rearward of the horizontal portion (24H). The horizontal portion (24H) may protrude between the display panel (10) and the frame (80) from one side of the vertical portion (24V). The horizontal portion (24H) may be arranged parallel to the display panel (10) at the rear of the display panel (10). The support portion (813d) of the frame (80) may be bent from the bending portion (812) toward the horizontal portion (24H) and may be arranged at the rear of the horizontal portion (24H). The support portion (813d) may be arranged parallel to the horizontal portion (24H).

[0091] The vertical portion (24H) may overlap, at least in part, the side portion (93) of the back cover (90) in the left-right direction or the up-down direction along which one side of the display panel (10) extends. The vertical portion (24H) may surround the outside of the side portion (93) of the back cover (90). The distance (A) from the support portion (813d) to the rear end of the vertical portion (24V) may be greater than the distance (B) from the support portion (813d) to the front end of the side portion (93) of the back cover (90).

[0092] Accordingly, the vertical portion and the side portion of the back cover overlap to prevent light emitted from the internal backlight unit from leaking out of the display device. In addition, foreign substances can be prevented from entering from the outside of the display device.

[0093] A gap (G2) may be formed between the vertical portion (24V) and the side portion (93) of the back cover (90). The width of the gap (G2) may be defined as the shortest distance between the inner surface of the vertical portion (24V) and the side portion (93) of the back cover (90). The width of the gap (G2) may be smaller than the length by which the catch (943) of the fastening portion (94) protrudes from the fastening leg (942).

[0094] A gap (G2) is formed, but the width of the gap (G2) is formed to be smaller than the protruding length of the catch (943), thereby ensuring ease of fastening between the back cover and the frame.

[0095] The latch (82) can be coupled or coupled with the fastening portion (94). The latch (82) can be seated in the groove (G1) formed in the fastening portion (94). The protrusion (821) of the latch (82) can be caught in the catch (943) of the fastening portion (94). In a state where the latch (82) and the fastening portion (94) are coupled or coupled, the first curved portion (R1) and the third curved portion (R3) can face each other, and the second curved portion (R2) and the fourth curved portion (R4) can face each other.

[0096] The radius of curvature of the third curved portion (R3) may be larger than the radius of curvature of the first curved portion (R1). That is, the first curved portion (R1) may have a relatively sharper shape than the third curved portion (R3). The radius of curvature of the fourth curved portion (R4) may be smaller than the radius of curvature of the second curved portion (R2). That is, the fourth curved portion (R4) may have a relatively sharper shape than the second curved portion (R2).

[0097] Accordingly, the latch (82) can be more stably engaged with the fastening portion (94), and the back cover (90) can be more firmly fixed to the frame (80).

[0098]

[0099] Referring to FIG. 13, the angle (Ag1) at which the first inclined portion (S1) of the latch (82) is inclined backward with respect to the left-right direction or the up-down direction in which one side of the display panel (10) extends may be greater than the angle (Ag2) at which the second inclined portion (S2) of the fastening portion (94) is inclined forward with respect to the left-right direction or the up-down direction in which one side of the display panel (10) extends.

[0100] In the process of combining the frame (80) and the back cover (90), the first inclined portion (S1) of the latch (82) comes into contact with the second inclined portion (S2) of the fastening portion (94), and as the first inclined portion (S1) slides against the second inclined portion (S2), the protrusion (821) of the latch (82) can be inserted into the groove (G1) of the fastening portion (94).

[0101] Accordingly, during the process of attaching or fastening the back cover to the frame, the latch can be more easily attached to the fastening member by the first / second inclined portion, thereby enhancing assembly convenience. Furthermore, since a separate structure for attaching the back cover to the frame is not required, the assembly structure of the device can be simplified. Furthermore, the number of screws required for attaching the back cover to the frame can be minimized, thereby reducing manufacturing costs.

[0102] When the latch (82) is coupled or fastened to the fastening portion (84), the latch (82) and the fastening leg (942) can be spaced apart by a certain distance. In the left-right direction or the up-down direction in which one side of the display panel (10) extends, the shortest distance in which the latch (82) and the fastening leg (942) are spaced apart may be D1. When the latch (82) is coupled or fastened to the fastening portion (84), the second curved portion (R2) and the catch (943) can be spaced apart by a certain distance. In the left-right direction or the up-down direction in which one side of the display panel (10) extends, the shortest distance in which the second curved portion (R2) and the catch (943) are spaced apart may be D2. D1 can be greater than D2. That is, when the latch (82) is coupled or fastened to the fastening portion (84), the shortest distance (D1) between the latch (82) and the fastening leg (942) may be greater than the shortest distance (D2) between the second curved portion (R2) and the catch (943).

[0103] Accordingly, the latch can be more easily attached to the fastener, increasing assembly convenience. Furthermore, the latch can be more securely engaged with the fastener, and the back cover can be more firmly secured to the frame.

[0104] When the latch (82) is coupled or fastened to the fastening portion (84), the latch (82) and the fastening body (941) can be spaced apart by a certain distance. In the front-back direction, the shortest distance that the latch (82) and the front surface (9411) of the fastening body (941) are spaced apart from each other may be D3. When the latch (82) is coupled or fastened to the fastening portion (84), the first curved portion (R1) and the third curved portion (R3) can be spaced apart by a certain distance, and the second curved portion (R2) and the fourth curved portion (R4) can be spaced apart by a certain distance. The shortest distance among the distances that the first curved portion (R1) and the third curved portion (R3) are spaced apart from each other and the distances that the second curved portion (R2) and the fourth curved portion (R4) are spaced apart from each other may be D4. D3 may be greater than D4. That is, the shortest distance (D3) between one side (9411) of the fastening body (941) connected to one end of the fastening leg (942) and the latch (82) may be greater than the shortest distance between the first curved portion (R1) and the third curved portion (R3) and the shortest distance (D4) between the second curved portion (R2) and the fourth curved portion (R4).

[0105] Accordingly, the latch can be more easily attached to the fastener, increasing assembly convenience. Furthermore, the latch can be more securely engaged with the fastener, and the back cover can be more firmly secured to the frame.
