The display device may include a rear cover (80) coupled to the rear of the rear chassis (100) to form the rear exterior of the display device together with the rear chassis (100).

[0040] According to one embodiment, a reflective sheet that reflects light emitted through the rear surface of the light guide plate (30) forward may be disposed at the rear of the light guide plate (30).

[0041] The display panel (10) is composed of a liquid crystal display panel using liquid crystal and may include a thin film transistor substrate having a thin film transistor (TFT) formed thereon, a color filter substrate facing the thin film transistor substrate, and liquid crystal provided between the thin film transistor substrate and the color filter substrate.

[0042] The thin-film transistor substrate may be a transparent glass substrate on which a thin-film transistor, which is a switching element, is formed in a matrix form.

[0043] A data line is connected to the source terminal of the thin-film transistors, a gate line is connected to the gate terminal, and a pixel electrode made of a transparent conductive material can be connected to the drain terminal.

[0044] The color filter substrate may be a substrate formed by a thin-film process in which RGB (Red, Green, Blue) pixels, which are color pixels that express a predetermined color when light passes through, are arranged oppositely to the thin-film transistor substrate at a certain distance.

Since a separate component such as a screw is not required, the process of mounting the first circuit board (50, 60) on the bracket (200) is simplified, and productivity can be improved. In addition, since a separate component such as a screw is not required, the structure can be simplified.

[0081] In addition, as described above, a bracket (200) is attached to the front of the rear chassis (100), and a first circuit board (50, 60) is seated on the bracket (200) at the rear of the rear chassis (100), so the rear chassis (100) can be positioned between the bracket (200) and the first circuit board (50, 60). Since the injection-molded rear chassis (100) is positioned between the bracket (200) and the first circuit board (50, 60), a separate sheet for insulating the first circuit board (50, 60) may not be required. That is, if the rear chassis (100) is made of metal, a separate sheet may be required between the rear chassis (100) and the first circuit board (50, 60) to insulate the first circuit board (50, 60), but since the rear chassis (100) can be injection molded, a separate sheet to insulate the first circuit board (50, 60) may not be required. For example, the rear chassis (100) may be formed of an insulating material (e.g., a polymer material used in the injection molding process of the rear chassis (100) (e.g., plastic)).

[0082] Next, with reference to FIGS. 4 to 14, we will examine in detail the process of the bracket (200) being attached to the front of the rear chassis (100) and the process of the first circuit board (50, 60) being seated on the bracket (200) at the rear of the rear chassis (100).

[0085] When a plurality of second connecting ribs (221) are connected to a plurality of second connecting holes (112), as shown in FIG. 6, a plurality of second hooks (223) of the second bracket (220) can be pushed into a plurality of fourth connecting holes (114) of the rear chassis (100) to be hook-connected.

[0086] As illustrated in FIG. 7, since a protrusion (115) can be formed in each of the plurality of fourth coupling holes (114), when a plurality of second hooks (223) are pushed into the plurality of fourth coupling holes (114), each of the plurality of second hooks (223) can be fixed to the protrusion (115). Each of the plurality of second hooks (223) is fixed to the protrusion (115), and the plurality of second hooks (223) can be hook-coupled to the plurality of fourth coupling holes (114).
