The back cover <NUM> is connected to the frame <NUM> through the bracket <NUM>, and its movement may be constrained and restricted within a predetermined range. That is, the back cover <NUM> is fixed to the frame <NUM> via the bracket <NUM>.

More specifically, the bracket <NUM> may be disposed in an inner space provided between the frame <NUM> and the back cover <NUM>. The bracket <NUM> may include a body <NUM> with a predetermined shape. The body <NUM> includes at least a first surface P1 and a second surface P2. That is, the first surface P1 and the second surface P2 may refer to predetermined different surfaces among surfaces that determine an appearance of the body <NUM>.

The first surface P1 of the body <NUM> may be a surface facing the extension <NUM> of the frame <NUM>. That is, the first surface P1 may be a surface facing a rear surface of the extension <NUM>. Alternatively, the first surface P1 may be a surface that contacts at least a portion of the rear surface of the extension <NUM>. When the extension <NUM> contacts face-to-face with the bracket <NUM> as described above, it may be easy to maintain a state in which the extension <NUM> is seated on the first surface P1 of the body <NUM>. The first surface P1 may be referred to as an upper surface of the body <NUM>.

The bracket <NUM> and the frame <NUM> are fixed to each other through a predetermined fastening structure.

For example, referring to <FIG>, the frame <NUM> and the bracket <NUM> may be fixed to each other through at least one screw <NUM>. For example, the body <NUM> of the bracket <NUM> and the extension <NUM> of the frame <NUM> may respectively include a first screw hole <NUM> and a second screw hole <NUM> that are opened along one direction.

As another example, referring to <FIG>, the frame <NUM> and the bracket <NUM> may be fixed to each other through an adhesive member <NUM> interposed between the extension <NUM> of the frame <NUM> and the body <NUM> of the bracket <NUM>. The adhesive member <NUM> may be a double-sided tape, but is not limited thereto. One surface of the adhesive member <NUM> may be attached to the rear surface of the extension <NUM>, and other surface of the adhesive member <NUM> may be attached to the first surface P1 of the body <NUM>.

As another example, referring to <FIG>, the frame <NUM> and the bracket <NUM> may be fixed to each other through a fitting coupling structure. The bracket <NUM> may include at least one fixing pin <NUM>, and the extension <NUM> of the frame <NUM> may include a pin hole <NUM>. For example, the fixing pin <NUM> may have a shape protruding from the first surface P1 of the body <NUM> toward the extension <NUM>. The fixing pin <NUM> may include a pin head <NUM> and a pin neck 421N. Each of the pin head <NUM> and the pin neck 421N may have a cylindrical shape having a different diameter.

The pin head <NUM> may extend from the pin neck 421N and may have a cylindrical shape having a second diameter larger than the first diameter. A diameter of the pin hole <NUM> may be set to be greater than or equal to the first diameter, but may be set to be less than the second diameter. The bracket <NUM> may be formed of a material with a predetermined softness. Thus, when a predetermined external force is provided, the pin head <NUM> may pass through the pin hole <NUM>. Thereafter, since the movement of the pin head <NUM> through the pin hole <NUM> is restricted, the frame <NUM> and the bracket <NUM> may be kept fixed to each other.

Referring to <FIG>, the bracket <NUM> may further include at least one protrusion <NUM>. The extension <NUM> of the frame <NUM> may include an open hole <NUM> into which the protrusion <NUM> is inserted. The number of protrusions <NUM> may correspond to the number of open holes <NUM>. As the protrusion <NUM> is inserted into the open hole <NUM>, a relative rotational motion (or twist) of the bracket <NUM> and the frame <NUM> may be restricted. Hence, there is an advantage in that the movement of the frame <NUM> and the bracket <NUM> can be more effectively constrained. Here, an extension direction of the protrusion <NUM> may be a direction perpendicular to the extension direction of the extension <NUM>.

Referring again to <FIG> and <FIG>, the second surface P2 of the body <NUM> may be a surface extending from one side of the first surface P1 toward the rear.

The second surface P2 may be a surface that contacts at least a portion of one end of the back cover <NUM>. The second surface P2 may be referred to as a side surface of the body <NUM>.

The body <NUM> may include a fitting groove <NUM>. The fitting groove <NUM> may be provided corresponding to the second surface P2 of the body <NUM>. The fitting groove <NUM> may be provided in a shape in which the second surface P2 of the body <NUM> is partially recessed inward.

The back cover <NUM> may include a base portion <NUM>, a connection portion <NUM>, and a coupling portion <NUM>. The base portion <NUM> may cover the rear surface of the frame <NUM>. The connection portion <NUM> is a bent portion of the back cover <NUM> and may extend from one end of the base portion <NUM>. The connection portion <NUM> may cover at least a portion of the second surface P2 of the body <NUM>. The coupling portion <NUM> may protrude inward from one end of the connection portion <NUM> toward the bracket <NUM>. A shape of the coupling portion <NUM> may correspond to the shape of the fitting groove <NUM>.

The coupling portion <NUM> may be inserted into the fitting groove <NUM>. Hence, the mutual movement of the back cover <NUM> and the bracket <NUM> may be restricted and constrained. That is, the bracket <NUM> and the back cover <NUM> may be fastened through a snap fit structure using the coupling portion <NUM> and the fitting groove <NUM>. A protruding direction of the coupling portion <NUM> may be a horizontal direction intersecting the fastening direction of the screw <NUM> and/or the extension direction of the protrusion <NUM>.

Since the fitting groove <NUM> and the coupling portion <NUM> which are used in the fastening structure of the bracket <NUM> and the back cover <NUM> are not visually recognized from the outside, there is an advantage in that a display device with a neat appearance can be provided. In addition, since the process can be simplified by using the snap fit structure, there is an advantage in that the manufacturing yield can increase, and the manufacturing time and manufacturing cost can be reduced. In addition, by using the snap fit structure, there is an advantage of increasing the convenience of maintenance.

More specifically, referring to <FIG> and <FIG> together with <FIG>, the back cover <NUM> is fastened to the bracket <NUM> fixed to the frame <NUM>. Hence, the back cover <NUM> may be fixed to the frame <NUM> by means of the bracket <NUM>.

The coupling portion <NUM> of the back cover <NUM> may be inserted into the fitting groove <NUM> provided in the body <NUM> of the bracket <NUM>. The coupling portion <NUM> may have a curling shape in which one end of the back cover <NUM> is rolled round. In this case, since the rigidity of the coupling portion <NUM> can be improved, there is an advantage in that damage to the coupling portion <NUM> can be prevented during fitting coupling.

The fitting groove <NUM> may have a shape corresponding to the shape of the coupling portion <NUM>. For example, when the coupling portion <NUM> has the curling shape, curvature forming an outer shape of the curling shape and curvature of the fitting groove <NUM> may correspond to each other. That is, the curvature forming the outer periphery of the coupling portion <NUM> and the curvature of the fitting groove <NUM> that contacts the coupling portion <NUM> to correspond thereto may be the same as each other. In this case, the coupling portion <NUM> may be firmly fastened to the fitting groove <NUM>. Hence, since a clearance between the coupling portion <NUM> and the fitting groove <NUM> can be minimized, damage and noise due to the clearance between the coupling portion <NUM> and the fitting groove <NUM> can be prevented.

The bracket <NUM> may further include a guide portion <NUM>. The guide portion <NUM> may extend from the second surface P2 of the body <NUM> and may have a shape protruding toward the connection portion <NUM> of the back cover <NUM>. The guide portion <NUM> may serve as a stopper that prevents the coupling portion <NUM> inserted into the fitting groove <NUM> from being separated from a predetermined fixed position.

The guide portion <NUM> may include a guide surface <NUM> facing the connection portion <NUM> of the back cover <NUM>. At least a portion of the guide surface <NUM> may contact face-to-face with the connection portion <NUM> of the back cover <NUM>. In this case, the back cover <NUM> may be stably seated at the proper position of the bracket <NUM>.

When the back cover <NUM> and the bracket <NUM> are assembled, the guide surface <NUM> may guide a movement path of the coupling portion <NUM>. To this end, the guide surface <NUM> may have a bent portion <NUM>. The bent portion <NUM> may extend toward the inward direction as it goes to the rear. In other words, the bent portion <NUM> may be bent more than once in a predetermined direction, and the predetermined direction may be directed toward the inward direction as it goes to the rear. The bent portion <NUM> is not limited to the illustrated structure, and may have a multi-bending structure, if necessary. In this case, in the process of fastening the bracket <NUM> and the back cover <NUM>, there is an advantage in that the coupling portion <NUM> can be fitted and coupled to the fitting groove <NUM> with a relatively small force. In addition, since the external force provided is reduced, there is an advantage of preventing damage to the bracket <NUM> and the back cover <NUM>.

Certain embodiments or other embodiments of the present disclosure described above are not mutually exclusive or distinct from each other. Some embodiments or other embodiments of the present disclosure described above may be combined with each other in configuration or function.
