[0095] The side frame (140) can be formed by bending, or it can be formed by combining separate frames.

[0096] Referring to FIG. 13, the side frame (140) may include an outer frame (141) and an inner frame (143). The outer frame (141) may form the outer edge of the side frame (140). The outer frame (141) may form the first long side (LS1), the first short side (SS1), and the second short side (SS2) of the display device (100). The outer frame (141) may be formed integrally, or may be formed separately and each may be combined.

[0097] The inner frame (143) may be connected to the outer frame (141). The inner frame (143) may extend from the outer frame (141). There may be multiple inner frames (143).

At this time, the third inner frame (143SS2) may be a long, extended flat plate. The outer frame (141) may form the overall framework of the side frame (140). The inner frame (143) is connected to the outer frame (141) and can provide support to the components of the display device (100).

[0099] The reinforcing member (145) may be located at the first corner (C1) and / or the second corner (C2). The reinforcing member (145) may be located on the inner side of the outer frame (141) adjacent to the first corner (C1).

The three grooves (140h) may be formed sequentially in the inner frame (143SS1) of the first short side, and the spacing may be regular.

[0101] Referring to FIG. 14, the reinforcing member (145) may have a straight section (145L) and a rounded section (145R).

[0104] FIGS. 15 to 29 are drawings illustrating examples of the assembly of a display device according to one embodiment of the present invention.

[0105] Referring to FIG. 15, the optical sheet (125) may be located inside the side frame (140). The optical sheet (125) may be coupled to the side frame (140). The optical sheet (125) may be coupled to the inside of the side frame (140). The optical sheet (125) may be fitted into a groove (140h) provided in the side frame (140).

[0106] The optical sheet (125) can ensure that light from a light source is evenly transmitted to the display panel (110). The optical sheet (125) may be composed of a plurality of layers. For example, it may include at least one prism sheet and / or at least one diffusion sheet. The optical sheet (125) may have at least one coupling portion (125d). The coupling portion (125d) may be coupled to a groove (140h) of the side frame (140). The coupling portion (125d) may be formed on a first long side, a first short side, and / or a second short side of the optical sheet (125).

[0107] The optical sheet (125) may be composed of a plurality of sheets having different functions. For example, the optical sheet (125) may include first to third optical sheets. The first optical sheet may have the function of a diffusion sheet, and the second and third optical sheets may have the function of prism sheets. The number and / or position of the diffusion sheets and prism sheets may be changed. For example, this means that it may include a first optical sheet which is a diffusion sheet and a second optical sheet which is a prism sheet.

[0108] The diffusion sheet can prevent the light coming from the diffusion plate from being partially concentrated, thereby making the distribution of light more uniform. The prism sheet can concentrate the light coming from the diffusion sheet so that the light is incident perpendicularly on the display panel (110).

[0109] A connecting portion (125d) may be formed on at least one of the corners of the optical sheet (125). A connecting portion (125d) may be formed on at least one of the first to third optical sheets. A connecting portion (125d) may be formed on the long side corner of the optical sheet (125). The connecting portion (125d) formed on the first long side may have an irregular arrangement. For example, this means that the position and / or number of connecting portions (125d) on the first long side and the connecting portions (125d) on the first or second short side may differ from each other.

[0110] At least one optical assembly (124) may be mounted on the substrate (122). The substrate (122) may have an electrode pattern formed thereon for connecting the adapter and the optical assembly (124). For example, the substrate (122) may have a carbon nanotube electrode pattern formed thereon for connecting the optical assembly (124) and the adapter. The substrate (122) may be composed of at least one of polyethylene terephthalate (PET), glass, polycarbonate (PC), and silicon. The substrate (122) may be a Printed Circuit Board (PCB) on which at least one optical assembly (124) is mounted.

[0111] The light assembly (124) may be a light-emitting diode (LED) chip or a light-emitting diode package including at least one light-emitting diode chip. The light assembly (124) may be composed of a colored LED or a white LED that emits at least one color among colors such as red, blue, and green. The colored LED may include at least one of a red LED, a blue LED, and a green LED.

[0112] The light source included in the light assembly (124) may be of the COB (Chip On Board) type. The COB type may be a form in which an LED chip, which is the light source, is directly combined to the substrate (122). Therefore, the process can be simplified. In addition, the resistance can be lowered, and thus the energy lost as heat can be reduced. That is, it means that the power efficiency of the light assembly (124) can be increased. The COB type can provide brighter illumination. The COB type can be implemented thinner and lighter than conventional types.

[0113] The optical layer (123) can evenly provide light from the optical assembly (124) to the rear surface of the display panel (110). That is, the optical layer (123) can diffuse the light provided by the optical assembly (124). For example, the optical layer (123) may be a light guide panel. The light provided from the optical assembly (124) to the optical layer (123) may be totally reflected within the optical layer (123) and dispersed throughout the optical layer (123). The optical layer (123) may be located behind the optical sheet (125). The substrate (122) and / or the optical assembly (124) may be located on one side of the optical layer (123). For example, the substrate (122) and / or the optical assembly (124) may be located below the optical layer (123).

[0114] Referring to FIG. 16, the locking portion (142) may be located in the groove (140h). The locking portion (142) may be located in the groove (140h) formed in the inner frame (143). The locking portion (142) may be provided with a supporter (142a), a pipe (142b), and a projection (142c). The supporter (142a) may protrude from the groove (140h) of the inner frame (143) and may be extended. The length of the supporter (142a) may be equal to or slightly different from the length of the coupling portion (125d) of the optical sheet (125). That is, the coupling portion (125d) of the optical sheet (125) may be held in position by the supporter (142a).

[0115] The pipe (142b) may be formed extending from the top of the supporter (142a) in the direction of extension of the supporter (142a). The thickness of the pipe (142b) may be greater than the thickness of the supporter (142a). That is, it may be larger than the width of the connecting portion (125d) of the optical sheet (125). In other words, while the connecting portion (125d) of the optical sheet (125) is fitted into the supporter (142a), the pipe (142b) can prevent the connecting portion (125d) of the optical sheet (125) from being detached from the supporter (142a). Protrusions (142c) may be formed at both ends of the pipe (142b). After the coupling portion (125d) of the optical sheet (125) is fitted into the supporter (142a) by the protrusion (142c), the optical sheet (125) can be more effectively prevented from detaching from the supporter (142a).

[0119] The reflective sheet (126) may include at least one of a metal and a metal oxide that is a reflective material. For example, the reflective sheet (126) may include a metal and / or a metal oxide having a high reflectivity, such as at least one of aluminum (Al), silver (Ag), gold (Au), and titanium dioxide (TiO2).

[0120] The reflective sheet (126) can be formed by depositing and / or coating a metal or metal oxide on a substrate (122). The reflective sheet (126) may have ink containing a metal material printed on it. The reflective sheet (126) may have a deposited layer formed using a vacuum deposition method such as thermal evaporation, evaporation, or sputtering.
