For example, while the supporter (110) supports the optical member (40) and / or the display panel (20), the display panel (20) and / or the optical member (40) may receive an impact.

[0090] As the display panel (20) receives an impact, the display panel (20) may undergo a slight elastic deformation, and the supporter (110) supporting the display panel (20) may also undergo an elastic deformation in the -X direction. For example, the supporter (112) of the supporter (110) may undergo an elastic deformation. Based on the display panel (20) and the supporter (112) being elastically deformed in the -X direction, the buffer member (120) may come into contact with the optical member (40) to alleviate the impact.

[0091] The supporter (110) may be configured to be elastically deformable. The supporter (110) may include an extension (111) and a support (112). However, only the support (112) may be provided.

[0092] The extension (111) may extend from the base (100a) toward the display panel (20) and / or the optical member (40). The extension (111) may be elastically deformable.

[0093] The support member (112) may extend from the extension member (111) toward the display panel (20) and / or the optical member (40). The support member (112) may support the display panel (20) and the optical member (40). The support member (112) may be in contact with the optical member (40). The support member (112) may include a support surface (112a). The support surface (112a) may be in contact with the optical member (40). For example, the support surface (112a) may be provided at one end of the support member (112) along the X direction. Accordingly, the support surface (112a) may be in contact with one surface of the optical member (40) along the -X direction.

[0094] The buffer member (120) may include a leg (121) and a contact portion (122).

[0095] The leg (121) may extend from the base (100a) toward the display panel (20) and / or the optical member (40). The leg (121) may be elastically deformable to alleviate impact transmitted to the buffer member (120). For example, based on the display panel (20) receiving an impact and elastic deformation occurring in the display panel (20), the leg (121) may be deformed in the -X direction to alleviate impact.

[0096] The contact portion (122) may extend from the leg (121) toward the display panel (20) and / or the optical member (40). Based on the fact that the display panel (20) is elastically deformed when the display panel (20) receives an impact, the contact portion (122) may come into contact with the optical member (40) to alleviate the impact. The contact portion (122) may include a contact surface (122a). The contact surface (122a) may come into contact with the optical member (40). For example, the contact surface (122a) may be provided at one end of the contact portion (122) along the X direction. Therefore, based on the fact that the display panel (20) is elastically deformed when the display panel (20) receives an impact, the contact surface (122a) may come into contact with one side of the optical member (40) along the -X direction.

[0097] The support surface (112a) may have a small area (A1) so as not to be visible on the display panel (20). The contact surface (122a) may have a larger area (A2) than the support surface so as to disperse and alleviate impact.

[0098] One end (122a) adjacent to the optical member (40) of the buffer member (120) may be spaced apart from the optical member (40) and the display panel (20). Therefore, when no external impact is applied, the buffer member (120) may not come into contact with the optical member (40), and the buffer member (120) may not be visible on the display panel (20).

[0099] The area (A2) of the contact surface (122a) may be larger than the area (A1) of the support surface (112a). Therefore, based on the display panel (20) being elastically deformed when receiving an impact, the contact surface (122a) can alleviate the impact more than the support surface (112a).

[0100] The distance (d2) between the buffer member (120) and the display panel (20) may be longer than the distance (d1) between the supporter (110) and the display panel (20). For example, the distance (d2) between the contact surface (122a) and the display panel (20) may be longer than the distance (d1) between the support surface (112a) and the display panel (20). Therefore, when the display panel (20) receives an impact and elastic deformation occurs in the display panel (20), the contact surface (122a) may come into contact with the optical member (40) based on the deformation of the display panel (20) and the supporter (110), thereby alleviating and dispersing the impact.

[0101] Due to an external impact of the display device, the display panel (20) and the optical member (40) may be elastically deformed, and thus, impact or pressure may be applied to the supporter (110). When impact or pressure is applied to the supporter (110), a part of the extension portion (111) connected to the support portion (112) may bend, and the support portion (112) may move in the -X direction. As the support portion (112) moves in the -X direction, the contact portion (122) comes into contact with the optical member (40), and the impact transmitted to the display panel (20) and the optical member (40) through the contact surface (122a) is transmitted to the buffer member (140), so that the impact transmitted to the display panel (20) and the optical member (40) may be dispersed and mitigated.

[0102] The support plate (100) can support the optical member (40) and the display panel (20) through the supporter (110), while at the same time alleviating external impact through the buffer member (120). Therefore, by performing multiple functions through one support plate (100), the production cost and material cost of the display device can be reduced, and production and manufacturing efficiency can be increased.

[0103] The support plate (100) can be slidably coupled to the bottom chassis (13). The support plate (100) can have a first position (P1) and a second position (P2). The support plate (100) can be slidably moved to the first position (P1) and the second position (P2). For example, the first position (P1) of the support plate (100) can be a position where the support plate (100) can be separated from the bottom chassis (13), and the second position (P2) of the support plate (100) can be a position where the support plate (100) can be moved from the first position (P1) and fixed to the bottom chassis (13).

[0104] The support plate (100) may be coupled, fixed and / or mounted to the bottom chassis (13). For example, the support plate (100) may include mounting holes (101, 102, 103), and the bottom chassis (13) may include mounting protrusions (15, 16) that are inserted into the mounting holes (101, 102, 103).

[0105] The mounting protrusions (15, 16) may protrude in the X direction from the chassis base (13a). For example, the mounting protrusions (15, 16) may protrude from the chassis base (13a) toward the optical member (40). The mounting protrusions (15, 16) may include a plurality of mounting protrusions (15, 16). The plurality of mounting protrusions (15, 16) may include a first mounting protrusion (15) and a second mounting protrusion (16). The first mounting protrusion (15) and the second mounting protrusion (16) may be spaced apart from each other.

[0106] The first mounting protrusion (15) may be arranged within the first mounting hole (101). For example, the first mounting protrusion (15) may be arranged and / or positioned in the first part (101a) of the first mounting hole (101) at the first position (P1) of the support plate (100) (see FIGS. 11 and 12). In addition, the first mounting protrusion (15) may be arranged and / or positioned in the second part (101b) of the first mounting hole (101) at the second position (P2) of the support plate (100) (see FIGS. 6 and 8).

[0107] The first mounting protrusion (15) may be covered by the cover portion (105). For example, the cover portion (105) may protrude forward from the base (100a) and cover the front of the first mounting protrusion (15).

[0108] The second mounting protrusion (16) can be arranged and positioned within the second mounting hole (102) or the third mounting hole (103). For example, the second mounting protrusion (16) can be arranged and / or positioned in the second mounting hole (102) at the first position (P1) of the support plate (100) (see FIGS. 11 and 12). In addition, the second mounting protrusion (16) can be arranged and / or positioned in the third mounting hole (103) at the second position (P2) of the support plate (100) (see FIGS. 6 and 8).

[0109] The mounting holes (101, 102, 103) may be formed by penetrating the base (100a). The mounting holes (101, 102, 103) may include a plurality of mounting holes (101, 102, 103). The plurality of mounting holes may include a first mounting hole (101), a second mounting hole (102), and a third mounting hole (103). A first mounting protrusion (15) may be inserted into the first mounting hole (101), and a second mounting protrusion (16) may be inserted into the second mounting hole (102) and the third mounting hole (103). The third mounting hole (103) may have a smaller area than the second mounting hole (102).

[0110] The first mounting hole (101) may include a first portion (101a) and a second portion (101b). The second portion (101b) may have a smaller area than the first portion (101a). The area of ​​the second portion (101b) may be smaller than the area of ​​the first portion (101a). The first mounting protrusion (15) may be positioned on the first portion (101a) at a first position (P1), and the first mounting protrusion (15) may be positioned on the second portion (101b) at a second position (P2). While the first mounting protrusion (15) is positioned on the second position (P2), the support plate (100) may be fixed to the bottom chassis (13).

[0111] The support plate (100) may include a step portion (100b). The step portion (100b) may have a step from the base (100a). The step portion (100b) may protrude from the base (100a) toward the first mounting hole (101). For example, the step portion (100b) may protrude from the base (100a) toward the second portion (101b) of the first mounting hole (101).

[0112] The first mounting protrusion (15) may include a recess (15a). The recess (15a) may be formed by being recessed from the outer surface of the first mounting protrusion (15). The recess (15a) may be recessed to correspond to the step portion (100b). The step portion (100b) may be accommodated in the recess (15a). Therefore, at the second position (P2), the support plate (100) is fixed by the first mounting protrusion (15) including the step portion (100b) and the recess (15a), so that the support plate (100) can be prevented from being detached in the X direction. In other words, at the second position (P2) of the support plate (100), the first mounting protrusion (15) is arranged in the second portion (101b) of the first mounting hole (101), so that the support plate (100) can be prevented from being detached.

[0114] Fig. 10 is an enlarged view showing that the support plate (100) shown in Fig. 6 has been moved. Fig. 11 is an enlarged view showing that the support plate (100) shown in Fig. 8 has been moved. Fig. 12 is a cross-sectional view taken along line F-F' of the display device shown in Fig. 11 showing that the support plate (100) shown in Fig. 9 has been moved.

[0115] FIGS. 5 to 8 illustrate that the support plate (100) is in the second position (P2), and FIGS. 10 to 12 illustrate that the support plate (100) is in the first position (P1).

[0116] Referring to FIGS. 10 to 12, the support plate (100) can be placed and / or positioned at the first position (P1).

[0117] At the first position (P1) of the support plate (100), the first mounting protrusion (15) can be arranged in the first part (101a) of the first mounting hole (101). Since the first mounting protrusion (15) is positioned in the first part (101a) having a larger area than the second part (101b) of the first mounting hole (101), the support plate (100) can be moved in the X direction. Therefore, at the first position (P1) of the support plate (100), the support plate (100) can be separated from the bottom chassis (13). For example, the support plate (100) can be separated from the bottom chassis (13) in the X direction.

[0118] Additionally, at the first position (P1) of the support plate (100), the second mounting protrusion (16) can be placed and positioned in the second mounting hole (102).

[0119] The support plate (100) may further include an inclined portion (104). The inclined portion may guide the movement of the support plate (100) while the support plate (100) is moved from a first position (P1) to a second position (P2). The inclined portion may be formed on a portion of the base (100a) forming the second mounting hole (102). While the support plate (100) is moved from the first position (P1) to the second position (P2), the second mounting protrusion (16) may move from the second mounting hole (102) to the third mounting hole (103) along the inclined portion (see FIG. 6).

[0120] In order to fix the support plate (100) to the bottom chassis (13), the support plate (100) located at the first position (P1) can be slidably moved to the second position (P2). At the second position (P2) of the support plate (100), the first mounting protrusion (15) can be placed in the second part (101b) of the first mounting hole (101), and the second mounting protrusion (16) can be placed and positioned in the third mounting hole (103).

[0121] In order to separate the support plate (100) from the bottom chassis (13), the support plate (100) positioned at the second position (P2) can be moved to the first position (P1). For example, the support plate (100) positioned at the second position (P2) can be slightly raised in the X direction to remove the second mounting protrusion (16) from the third mounting hole (103), and the support plate (100) can be moved in the -Y direction to be positioned at the first position (P1).

[0122] At the first position (P1) of the support plate (100), the first mounting protrusion (15) can be placed in the first part (101a) of the first mounting hole (101), and the second mounting protrusion (16) can be placed and positioned in the second mounting hole (102).

[0123] Even if the support plate (100) illustrated in FIGS. 4 to 12 is rotated 180 degrees, the support plate (100) can be mounted on the bottom chassis (13) and can move to a first position (P1) that is detachable from the bottom chassis (13) and a second position (P2) that is fixed to the bottom chassis (13).
