[0024] The directional indications of Up (U), Down (D), Left (Le), Right (Ri), Front (F), and Rear (R) shown in the drawings are for convenience of explanation only and do not limit the technical concepts disclosed in this specification.

[0026] Referring to FIG. 1, the display device (100) may include a display panel (110). The display panel (110) may display a screen.

[0027] A display device (100) may include a first long side (LS1), a second long side (LS2) facing the first long side (LS1), a first short side (SS1) adjacent to the first long side (LS1) and the second long side (LS2), and a second short side (SS2) facing the first short side (SS1). Meanwhile, for convenience of explanation, the lengths of the first and second long sides (LS1, LS2) are shown and described as being longer than the lengths of the first and second short sides (SS1, SS2), but it is also possible for the lengths of the first and second long sides (LS1, LS2) to be approximately the same as the lengths of the first and second short sides (SS1, SS2).

[0028] A direction parallel to the long side (LS1, LS2) of the display device (100) may be referred to as the first direction (DR1) or left-right direction. A direction parallel to the short side (SS1, SS2) of the display device (100) may be referred to as the second direction (DR2) or up-down direction. A direction perpendicular to the long side (LS1, LS2) and short side (SS1, SS2) of the display device (100) may be referred to as the third direction (DR3) or front-back direction.

[0029] The direction in which the display device (100) displays an image can be called the front (F, +z), and the opposite direction can be called the rear (R, -z). The second short side (SS2) can be called the left side (Le, -x). The first short side (SS1) can be called the right side (Ri, +x). The first long side (LS1) can be called the upper side (U, +y). The second long side (LS2) can be called the lower side (D, -y).

[0030] The first long side (LS1), the second long side (LS2), the first short side (SS1), and the second short side (SS2) can be referred to as edges of the display device (100). Additionally, the point where the first long side (LS1), the second long side (LS2), the first short side (SS1), and the second short side (SS2) meet each other can be referred to as a corner.

[0031] The point where the first short side (SS1) and the first long side (LS1) meet may be the first corner (C1). The point where the first short side (SS1) and the second long side (LS2) meet may be the second corner (C2). The point where the second short side (SS2) and the second long side (LS2) meet may be the third corner (C3). The point where the second short side (SS2) and the first long side (LS1) meet may be the fourth corner (C4).

[0032] Hereinafter, a display panel (110) is described using an organic light-emitting diode (OLED) as an example, but the display panel (110) applicable to the present disclosure is not limited thereto.

[0033] The display panel (110) forms the front surface of the display device (100) and can display an image forward. The display panel (110) can output an image by dividing the image into multiple pixels and adjusting the color, brightness, and saturation for each pixel. The display panel (110) can be divided into an active area where the image is displayed and a de-active area where the image is not displayed. The display panel (110) can generate light corresponding to the color red, green, or blue according to a control signal.

[0035] Referring to FIG. 2, the material complexed panel (130) may include a core (131), a front skin (132), and a rear skin (133). The core (131), the front skin (132), and the rear skin (133) may be combined with each other. The material complexed panel (130) may be referred to as a fiber complexed panel (130), a fiber complexed plate (130), a material complexed plate (130), or a frame (130).

[0036] The front skin (132) can form the front surface of the composite material panel (130). The rear skin (133) can form the rear surface of the composite material panel (130). The front skin (132) and the rear skin (133) may include a metal material. For example, the front skin (132) and the rear skin (133) may include an aluminum (Al) material. As another example, the front skin (132) and the rear skin (133) may be galvanized iron or galvanized steel sheet. For example, the thickness of the front skin (132) and the rear skin (133) may be about 0.5 mm. The front skin (132) and the rear skin (133) may face each other with respect to the core (131).

[0037] The core (131) may be located between the front skin (132) and the rear skin (133). The core (131) may include fibers. The core (131) may be formed from a composite material. The core (131) may include main fibers and binder fibers. Binder fibers may be mixed between the main fibers.

[0038] A hot-melt sheet may be positioned between the front skin (132) and the core (131). Additionally, a hot-melt sheet may be positioned between the rear skin (133) and the core (131). The hot-melt sheet may be a film. For example, the hot-melt sheet may be a film such as EVA, acrylic, or polyurethane having a thickness of 50 micrometers or more. The core (131) and the hot-melt sheet may be laminated to the front skin (132) and the rear skin (133) for at least 1 minute at a high temperature (e.g., about 190 to 200°C).

[0039] Accordingly, the composite material panel (130) can improve the bending rigidity and / or torsional rigidity of the display device.

[0041] Referring to FIGS. 3 and 4, a composite material panel (130) can be manufactured through a process of pressing a front skin (132) and a rear skin (133) onto a core (131) using a plurality of rollers, and this process can be called an R2R (Roll-to-Roll) process.

[0042] Referring to FIG. 3, depending on the rotation of the pinch roller (Ra) which performs the function of a drive motor, the front skin (132) can be released from the front drum (Da), the rear skin (133) can be released from the rear drum (Db), and the core (131) can be moved through the feeding roller (Rd). Also, a first adhesive (134a) for bonding the front skin (132) to the core (131) can be released from the first drum (Dc). Additionally, a second adhesive (134b) for bonding the rear skin (133) to the core (131) can be released from the second drum (Db). In this case, the front skin (132), the first adhesive (134a), the core (131), the second adhesive (134b), and the rear skin (133) can be laminated in the order above and guided toward the oven (Ov) by a guide roller (Rc). The adhesives (134a, 134b) may be hot-melt sheets (134a, 134b).

[0043] The first and second adhesives (134a, 134b) can be melted in an oven (Ov), and the front skin (132) and rear skin (133) can be bonded to the core (131). For example, the melting point of the first and second adhesives (134a, 134b) may be about 150°C, and the ambient temperature of the oven (Ov) may be about 200°C. For example, the peel-off force of the first and second adhesives (134a, 134b) may be about 10 kgf or more.

[0044] The front skin (132), core (131), and rear skin (133) that have passed through the oven (Ov) can be guided to the compression roller (Rb) according to the rotation of the pinch roller (Ra) and can be compressed by the compression roller (Rb). Accordingly, the bonding force between the front skin (132), core (131), and rear skin (133) can be further increased. After passing the pinch roller (Ra), the mutually bonded front skin (132), core (131), and rear skin (133) can be cut by a cutter (Ct) to be manufactured into a composite material panel (130) of a certain size.

[0045] Referring to FIG. 4, the compression roller (Rb) or pinch roller (Ra) may come into contact with the outer surface of the front skin (132) and the rear skin (133), respectively. When the compression roller (Rb) or pinch roller (Ra) rotates, the composite material panel (130) may be moved along the longitudinal direction of the core (131). At this time, along the longitudinal direction of the core (131), the front skin (132) and the rear skin (133) may be sequentially joined from one end of the core (131) to the other end.

[0046] Additionally, the front skin (132) and rear skin (133) of the composite material panel (130) can be formed flat. That is, by forming the rear surface of the rear skin (133) that forms the rear of the display device (100) flat, it becomes easier to perform additional work, such as painting or attaching a sheet to the rear surface of the rear skin (133) for aesthetic purposes. Alternatively, the flat rear skin (133) itself may form the rear surface of the display device (100).

[0047] Meanwhile, in addition to the R2R process described above with reference to FIGS. 3 and 4, a composite material panel (130) can be manufactured through a process such as stacking the front skin (132), core (131), and rear skin (133) in sequence and then combining them together.

[0049] Referring to FIG. 5, the core (131) may include a main core (131a) and a binder core (131b). The main core (131a) may have a first fiber made of PET (polyethylene terephthalate) material and a second fiber made of LM (long material) material. For example, the ratio of the first fiber to the second fiber in the main core (131a) may be 50%. The binder core (131b) may include an acrylic fiber.

[0050] The front skin (132) may be made of aluminum (Al) or galvanized iron and may be bonded to the binder core (131b) through a first hot-melt adhesive (134a).

[0051] The rear skin (133) may be made of aluminum (Al) or galvanized steel (Galvanized Iron) and may be bonded to the main core (131a) through a second hot-melt adhesive (134b).

[0052] The front skin (132) may be positioned closer to the display panel (110, see FIG. 16) than the rear skin (133) and may be exposed to a relatively high temperature environment than the rear skin (133). That is, a temperature difference may occur between the front skin (132) and the rear skin (133). For example, the temperature difference between the front skin (132) and the rear skin (133) may be about 4°C.

[0053] At this time, the hot-melt adhesive (134a, 134b) may be formed into a multilayer structure of fiber material. The hot-melt adhesive (134a, 134b) may include a first layer (1341), a second layer (1342), and a third layer (1343). For example, the first layer (1341), the second layer (1342), and the third layer (1343) may include synthetic fiber material. For example, the first layer (1341) may include nylon material and may be located between the second layer (1342) and the third layer (1343). For example, the second layer (1342) and the third layer (1343) may include polyurethane (PU) material.

[0054] Accordingly, due to the elongation characteristics of each layer of the composite material panel (130), the bending phenomenon caused by thermal deformation of the composite material panel (130) due to the temperature difference between the front skin (132) and the rear skin (133) can be minimized.

[0056] Referring to FIG. 6, the composite material panel (130) may include a flat portion (130P), an outer portion (135), and a receiving portion (137). The front skin (132) of the composite material panel (130) may define the front surface of each of the flat portion (130P), the outer portion (135), and the receiving portion (137).

[0057] The outer portion (135) may be formed around the perimeter of the flat portion (130P). The outer portion (135) may be formed by pressing backward from the flat portion (130P). The first outer portion (135a) may be formed along the upper edge of the flat portion (130P). The second outer portion (135b) may be formed along the right edge of the flat portion (130P). The third outer portion (135c) may be formed along the lower edge of the flat portion (130P). The fourth outer portion (135d) may be formed along the left edge of the flat portion (130P).

[0058] The receiving portion (137) may be formed between the flat portion (130P) and the third outer portion (135c). The receiving portion (137) may be formed by being pressed backward from the flat portion (130P) and / or the third outer portion (135c).

[0059] The cable hole (136) can be formed by penetrating the receiving portion (137) in the front-rear direction. For example, a plurality of cable holes (136a, 136b) can be adjacent to each other.

[0061] Referring to FIG. 7, the thickness (T1) of the flat portion (130P) may be greater than the thickness (T2) of the receiving portion (137). The step (D1) between the front skin (132) of the flat portion (130P) and the front skin (132) of the receiving portion (137) may be greater than the step (D2) between the rear skin (133) of the flat portion (130P) and the rear skin (133) of the receiving portion (137).

[0062] The thickness (T4) of the third outer portion (135c) may be greater than the thickness (T2) of the receiving portion (137). The step (D2) between the rear skin (133) of the third outer portion (135c) and the rear skin (133) of the receiving portion (137) may be the same as the step (D2) between the rear skin (133) of the flat portion (130P) and the rear skin (133) of the receiving portion (137).

[0063] The protruding pad (138) may protrude forward from the front skin (132) of the third outer portion (135c). The thickness (T3) of the protruding pad (138) may be greater than the thickness (T4) of the third outer portion (135c), greater than the thickness (T2) of the receiving portion (137), and smaller than the thickness (T1) of the flat portion (130P). The step (D4) between the front skin (132) of the protruding pad (138) and the front skin (132) of the third outer portion (135c) may be smaller than the step (D1, D2, D3). The step (D3) lowering from the front skin (132) of the protruding pad (138) to the front skin (132) of the receiving portion (137) may be smaller than the step (D1) and larger than the step (D2).

[0065] Referring to FIG. 8, the side frame (140) may extend along the perimeter of the composite panel (130). The side frame (140) may be bonded to the front skin (132) of the outer portion (135, see FIG. 6) of the composite panel (130) via hot-melt adhesive (130H). For example, the side frame (140) may comprise a metal material such as aluminum (Al). The side frame (140) may be referred to as a guide panel (140) or a middle cabinet (140).

[0067] Referring to FIGS. 9 and 10, the side frame (140) may include a vertical section (140V) and a horizontal section (140H). The vertical section (140V) may extend in the front-rear direction and may cover the side of the composite material panel (130). The horizontal section (140H) may extend from the vertical section (140V) in a direction intersecting the vertical section (140V) and may be located in front of the outer section (135).

[0068] Referring to FIG. 9, the outer portion (135) can be formed by pressing backward from the front skin (132) of the flat portion (130P). For example, the outer portion (135) can be re-striked and flattened after forging. For example, the thickness (T1) of the flat portion (130P) can be 4.0 mm, and the thickness (T4) of the outer portion (135) can be 3.0 mm. A hot-melt adhesive (130H) can be applied to the outer portion (135) and positioned between the outer portion (135) and the horizontal portion (140H).

[0069] Referring to FIG. 10, the horn (UW) of the ultrasonic welding machine may be positioned on the front of the horizontal portion (140H) and may apply ultrasonic vibrations to the horizontal portion (140H) and the hot-melt adhesive (130H). Accordingly, the horizontal portion (140H) may be ultrasonically welded to the outer portion (135) through the hot-melt adhesive (130H). At this time, the front skin (132) of the outer portion (135) may be pressed toward the rear skin (133) by the horn (UW), and the thickness (T5) of the outer portion (135) may be reduced. For example, the thickness (T5) of the outer portion (135) may be 2.4 to 2.5 mm. The amount of pressing (D6-D5) of the outer portion (135) by the horn (UW) may be 0.5 to 0.6 mm. Since the compression of these outer parts (135) is performed during the aforementioned ultrasonic welding, that is, at a high temperature, it can be maintained without springing back.

[0071] Referring to FIGS. 10 and 11, the sum (T10a) of the thickness (T5) of the outer portion (135), the thickness of the hot-melt adhesive (130H), and the thickness (T10) of the horizontal portion (140H) may be smaller than the thickness (T1) of the flat portion (130P). For example, the thickness (T1) of the flat portion (130P) may be 4.0 mm. For example, the thickness (T5) of the outer portion (135) may be 2.4 to 2.5 mm, the thickness of the hot-melt adhesive (130H) may be 0.1 mm, the thickness (T10) of the horizontal portion (140H) may be 1.1 mm, and the sum (T10a) of these may be 3.6 to 3.7 mm.

[0072] The display panel (110) may be located in front of the horizontal portion (140H). The first adhesive member (AD1) may be located between the front skin (132) of the flat portion (130P) and the rear surface of the display panel (110), and may be bonded to the flat portion (130P) and the display panel (110). For example, the thickness (T11) of the first adhesive member (AD1) may be 0.5 mm. The first adhesive member (AD2) may be located between the front surface of the horizontal portion (140H) and the rear surface of the display panel (110), and may be bonded to the horizontal portion (140H) and the display panel (110). For example, the thickness (T12) of the second adhesive member (AD2) may be 0.8 to 0.9 mm. For example, the adhesive members (AD1, AD2) may be double-sided tape.

[0073] Accordingly, the display panel (110) can be combined with the composite material panel (130) and the side frame (140), and can be positioned flat with respect to the composite material panel (130). In addition, the vertical portion (140V) can cover the side of the display panel (110).

[0075] Referring to FIG. 12 together with FIG. 8, the side frame (140) may include a first part (141), a second part (142), a third part (143), a fourth part (144), and a fifth part (145).

[0076] The first part (141) may extend along the first outer section (135a, see FIG. 6) and may include a first horizontal section (141H, see FIG. 9) and a first vertical section (141V). The first horizontal section (141H) may be parallel to the first outer section (135a) and may be fixed onto the first outer section (135a) via a hot-melt adhesive (130H). The first vertical section (141V) may intersect the first horizontal section (141H) and may cover the upper side of the composite panel (130).

[0077] The second part (142) may be bent downward from the right end of the first part (141) (see first corner (C1)) and may include a second horizontal section (142H) and a second vertical section (142V). The second horizontal section (142H) may be parallel to the second outer section (135b) and may be fixed onto the second outer section (135b) via a hot-melt adhesive (130H). The second vertical section (142V) may intersect the second horizontal section (142H) and may cover the right side of the composite panel (130).

[0078] The third part (143) may be bent to the left at the bottom of the second part (142) (see second corner (C2)) and may include a third horizontal section (143H, see FIG. 14) and a third vertical section (143V). The third horizontal section (143H) may be parallel to the third outer section (135c) and may be fixed onto the third outer section (135c) via a hot-melt adhesive (130H). The third vertical section (143V) may intersect the third horizontal section (143H) and may cover the lower side of the composite panel (130).

[0079] The fourth part (144) may be aligned with the third part (143) along the third outer part (135c), and the end of the fourth part (144) may be connected to the end of the third part (143). The fourth part (144) may include a fourth horizontal part (144H, see FIG. 15) and a fourth vertical part (144V, see FIG. 15). The fourth horizontal part (144H) may be parallel to the third outer part (135c) and may be fixed onto the third outer part (135c) via a hot-melt adhesive (130H). The fourth vertical part (144V) may intersect the fourth horizontal part (144H) and may cover the lower side of the composite panel (130).

[0080] The fifth part (145) may be bent downward from the left end of the first part (141) (see fourth corner (C4)), and the fourth part (144) may be bent to the right from the bottom of the fifth part (145) (see third corner (C3)). The fifth part (145) may include a fifth horizontal section (not shown) and a fifth vertical section (not shown).

There may be multiple line filters (LF1, LF2, LF3).

[0108] The first line (155a) may form a long side. The third line (155c) may face the first line (155a) and may be shorter than the first line (155a). The fifth line (155e) may face the first line (155a) and may be shorter than the first line (155a) and / or the third line (155c). The fifth line (155e) may be parallel to the third line (155c). The distance between the third line (155c) and the first line (155a) may be greater than the distance between the fifth line (155e) and the first line (155a). The second line (155b) forms a short side and can connect the first line (155a) and the third line (155c), and the sixth line (155f) forms a short side and can connect the first line (155a) and the fifth line (155e). The length of the second line (155b) may be greater than the length of the sixth line (155f). The sixth line (155f) may face the second line (155b). The fourth line (155d) can connect the third line (155c) and the fifth line (155e). The fourth line (155d) can form a slope with respect to the third line (155c). The fourth line (155d) can form a slope with respect to the fifth line (155e).

[0109] The first line filter (LF1) may be located between the first line (155a) and the third line (155c). The second line filter (LF2) may be located between the first line (155a) and the fourth line (155d) and / or the fifth line (155e). The third line filter (LF3) may be located between the first line (155a) and the fifth line (155e).

[0110] Line filters (LF1, LF2, LF3, LF) may be spaced apart from the lines (155a, 155b, 155c, 155d, 155e, 155f) of the opening (155) by a certain distance or more. Line filters (LF) and the lines (155a, 155b, 155c, 155d, 155e, 155f) of the opening (155) may be spaced apart from a first distance (A) or more. For example, the first line filter (LF1) may be spaced apart from the second line (155b) and / or the third line (155c) by a first distance (A) or more. As another example, the second line filter (LF2) may be spaced apart from the first line (155a) and / or the fifth line (155e) by a first distance (A) or more. As another example, the third line filter (LF3) may be spaced apart from the first line (155a) and / or the fifth line (155e) by a first distance (A). At the same time, the third line filter (LF3) may be spaced apart from the sixth line (155f) by a first distance (A).

[0111] The power supply unit (PSU) is spaced apart from the composite material panel (130) and the rear plate (150) and may be mounted or fixed to the rear of the rear plate (150). The power supply unit (PSU) may include a line filter (LF). For example, the line filter (LF) may include a coil and may remove noise from the power supply. An electromagnetic field may be formed around the line filter (LF). The rear plate (150) may vibrate due to the electromagnetic field generated while the line filter (LF) is operating. The vibration of the rear plate (150) may be transmitted to the composite material panel (130) and may cause vibration and / or noise. For example, as the display panel (110) becomes larger, the current value of the line filter (LF) increases, and the strength of the electromagnetic field generated by the line filter (LF) may increase. At this time, if the distance from the line filter (LF) to the rear plate (150) becomes closer, the vibration of the rear plate (150) increases, and if the distance from the line filter (LF) to the rear plate (150) becomes farther, the vibration of the rear plate (150) may decrease. The opening (155) of the rear plate (150) corresponding to the line filter (LF) can prevent the rear plate (150) from vibrating due to the line filter (LF). If the size of the opening (155) of the rear plate (150) formed to secure the distance between the line filter (LF) and the rear plate (150) increases, the rigidity of the rear plate (150) may decrease. Therefore, the distance between the line filter (LF) and the rear plate (150) formed by the opening (155) not only affects the rigidity of the rear plate (150), but also affects the noise and / or vibration generated in the rear plate (150). For example, the current flowing through the line filter (LF) is 3.5A to 4.3A, the second distance (B) from the line filter (LF) to the rear plate (150) may be 7 to 8 millimeters, and the first distance (A) from the line filter (LF) to the edge of the opening (155) of the rear plate (150) may be 15 millimeters or more. Accordingly, not only is the rigidity of the rear plate (150) secured, but vibration and / or noise of the rear plate (150) that may be generated by the driving of the line filter (LF) can also be prevented.

An insulating sheet (170) and / or a heat dissipation sheet (170) may be positioned between the power supply unit (PSU) and the back cover (180) and may be adhered to the back cover (180). The insulating sheet (170) and / or the heat dissipation sheet (170) may have an opening, and the line filter (LF) may be aligned with the opening.

A second opening (157) may be located adjacent to the first opening (155).

[0115] Line filters (LF1, LF2) of a power supply unit (PSU, see FIG. 25) may be located inside the first opening (155) between the lines (155a, 155b, 155c, 155d, 155e, 155f) of the first opening (155). Line filter (LF3) may be located in the second opening (157).

[0116] The first line (155a) may form a long side. The third line (155c) may face the first line (155a) and may be shorter than the first line (155a). The fifth line (155e) may face the first line (155a) and may be shorter than the first line (155a) and / or the third line (155c). The fifth line (155e) may be parallel to the third line (155c). The distance between the third line (155c) and the first line (155a) may be smaller than the distance between the fifth line (155e) and the first line (155a). The second line (155b) forms a short side and can connect the first line (155a) and the third line (155c), and the sixth line (155f) forms a short side and can connect the first line (155a) and the fifth line (155e). The length of the second line (155b) may be shorter than the length of the sixth line (155f). The sixth line (155f) may face the second line (155b). The fourth line (155d) can connect the third line (155c) and the fifth line (155e).

[0117] The first line filter (LF1) may be located between the first line (155a) and the third line (155c). Also, the first line filter (LF1) may be spaced apart from the second line (155b). The second line filter (LF2) may be located between the first line (155a) and the fifth line (155e). Also, the second line filter (LF2) may be spaced apart from the fourth line (155d) and / or the sixth line (155f). The third line filter (LF3) may be located inside the second opening (157). The third line filter (LF3) may be spaced apart from the edges of the second opening (157).

[0118] The line filters (LF1, LF2) may be spaced apart from the lines (155a, 155b, 155c, 155d, 155e, 155f) of the first opening (155) or the edges of the second opening (157) by a certain distance or more. The line filters (LF1, LF2) and the lines (155a, 155b, 155c, 155d, 155e, 155f) of the first opening (155) may be spaced apart from a first distance (A) or more.

[0119] For example, the first line filter (LF1) may be spaced apart from the first line (155a), the second line (155b), and / or the third line (155c) by a first distance (A). For another example, the second line filter (LF2) may be spaced apart from the fourth line (155d), the fifth line (155e), and / or the sixth line (155f) by a first distance (A). For another example, the third line filter (LF3) may be spaced apart from the edges of the second opening (157) by a first distance (A).

[0120] The power supply unit (PSU) is spaced apart from the composite material panel (130) and the rear plate (150) and may be mounted or fixed to the rear of the rear plate (150). The power supply unit (PSU) may include a line filter (LF). For example, the line filter (LF) may include a coil and may remove noise from the power supply. An electromagnetic field may be formed around the line filter (LF). The rear plate (150) may vibrate due to the electromagnetic field generated while the line filter (LF) is operating. The vibration of the rear plate (150) may be transmitted to the composite material panel (130) and may cause vibration and / or noise. For example, as the display panel (110) becomes larger, the current value of the line filter (LF) increases, and the strength of the electromagnetic field generated by the line filter (LF) may increase. At this time, when the distance from the line filter (LF) to the rear plate (150) decreases, the vibration of the rear plate (150) increases, and when the distance from the line filter (LF) to the rear plate (150) increases, the vibration of the rear plate (150) may decrease.

[0121] The openings (155, 157) of the rear plate (150) corresponding to the line filter (LF) can prevent the rear plate (150) from vibrating due to the line filter (LF). If the size of the opening (155) of the rear plate (150), which is formed to secure the distance between the line filter (LF) and the rear plate (150), increases, the rigidity of the rear plate (150) may decrease. Therefore, the distance between the line filter (LF) and the rear plate (150) formed by the opening (155) not only affects the rigidity of the rear plate (150), but also affects the noise and / or vibration generated in the rear plate (150).

[0122] For example, the current flowing through the line filter (LF) may be 2.8A to 3.2A, the second distance (B) from the line filter (LF) to the rear plate (150) may be 7 to 8 millimeters, and the first distance (A) from the line filter (LF) to the edge of the first opening (155) and / or the second opening (157) of the rear plate (150) may be 10 millimeters or more. Accordingly, not only is the rigidity of the rear plate (150) secured, but vibration and / or noise of the rear plate (150) that may be generated by the driving of the line filter (LF) can also be prevented.

[0124] Referring to FIGS. 22 and 23 together with FIG. 19, the opening (155) may include a first line (155a), a second line (155b), a third line (155c), a fourth line (155d), a fifth line (155e), and / or a sixth line (155f).

The fifth line (155e) may be parallel to the fourth line (155d). The fifth line (155e) may be formed by protruding from a portion of the fourth line (155d). The distance from the second line (155b) to the fifth line (155e) may be smaller than the distance from the second line (155b) to the fourth line (155d).

[0127] The length of the fifth line (155e) may be greater than the length of the sixth line (155f). The sixth line (155f) may face the second line (155b). The sixth line (155f) may connect the first line (155a) and the fourth line (155d).

[0128] The first line filter (LF1) may be located adjacent to the corner formed by the first line (155a) and the second line (155b). The second line filter (LF2) may be located adjacent to the corner formed by the first line and the sixth line, and may be located between the first line filter (LF1) and the fourth line (155d). The third line filter (LF3) may be located between the second line (155b) and the fourth line (155d). The fourth line filter (LF4) may be located between the second line (155b) and the fifth line (155e). The fifth line filter (LF5) may be located adjacent to the corner formed by the third line (155c) and the fourth line (155d) between the second line (155b) and the fourth line (155d).

[0129] The line filters (LF1, LF2, LF3, LF4, LF5, LF) may be spaced apart from the lines (155a, 155b, 155c, 155d, 155e, 155f) of the opening (155) by a certain distance or more. The line filters (LF) and the lines (155a, 155b, 155c, 155d, 155e, 155f) of the opening (155) may be spaced apart from a first distance (A) or more.

[0130] For example, the first line filter (LF1) may be spaced apart from the first line (155a) and / or the second line (155b) by a first distance (A). For another example, the second line filter (LF2) may be spaced apart from the fourth line (155d) and / or the sixth line (155f) by a first distance (A).

For another example, the fourth line filter (LF4) may be spaced apart from the fifth line (155e) by a first distance (A). For another example, the fifth line filter (LF5) may be spaced apart from the fourth line (155d) and / or the third line (155c) by a first distance (A).

[0131] The power supply unit (PSU) may be spaced apart from the composite material panel (130) and the rear plate (150), and may be mounted or fixed to the rear of the rear plate (150). The power supply unit (PSU) may include a line filter (LF). For example, the line filter (LF) may include a coil and may remove noise from the power supply. An electromagnetic field may be formed around the line filter (LF). The rear plate (150) may vibrate due to the electromagnetic field generated while the line filter (LF) is operating. The vibration of the rear plate (150) may be transmitted to the composite material panel (130) and may cause vibration and / or noise.

[0132] For example, as the display panel (110) becomes larger, the current value of the line filter (LF) increases, and the strength of the electromagnetic field generated by the line filter (LF) may increase. At this time, if the distance from the line filter (LF) to the rear plate (150) becomes closer, the vibration of the rear plate (150) may increase, and if the distance from the line filter (LF) to the rear plate (150) becomes farther, the vibration of the rear plate (150) may decrease. The opening (155) of the rear plate (150) corresponding to the line filter (LF) can prevent the rear plate (150) from vibrating due to the line filter (LF). If the size of the opening (155) of the rear plate (150) formed to secure the distance between the line filter (LF) and the rear plate (150) increases, the rigidity of the rear plate (150) may decrease. Accordingly, the distance of the rear plate (150) formed by the line filter (LF) and the opening (155) not only affects the rigidity of the rear plate (150), but also affects the noise and / or vibration generated in the rear plate (150).
