[0116]

[0117] Referring to Fig. 29, both ends of the bar (40) can be fixed to a belt (32). The left belt (32) can be wound around the left upper pulley (17) and the left drive pulley (31). The left belt (32) can move the left side of the bar (40) up and down when the left drive pulley (31) rotates. The right belt (32) can be wound around the right upper pulley (17) and the right drive pulley (31). The right belt (32) can move the right side of the bar (40) up and down when the right drive pulley (17) rotates.

[0118] As the bar (40) moves up and down, the horizontality of the bar (40) may not be secured. In addition, when initially setting the horizontality of the bar (40), it may be difficult to align the horizontality of the bar (40) due to the tolerance or play of the driving mechanism of the belt (32). If the horizontality of the bar (40) is not secured, the shade (45, see Fig. 17) cannot be maintained flat. If the shade (45) is not maintained flat, a part that comes into contact with the display panel (11, see Fig. 10) and / or the transparent panel (13) may be generated, and static electricity generated by friction between the shade (45) and the display panel (11) and / or the transparent panel (13) may adversely affect the performance of the display device.

[0119]

[0120] Referring to FIGS. 30 to 32, when the leveling shaft (425) is rotated, the moving block (423) moves up and down on the side body (422), so that the belt (32) and the belt fixer (43) can move up and down relative to the piece body (421, 422, see FIG. 27) of the bar (40). The block cover (426) is coupled to the side body (422) and can cover the moving block (423).

[0121] The moving block (423) can be in contact with or supported by the lower part (422b) of the side body (422). The moving block (423) can move upward by the rotation of the leveling shaft (425). When the moving block (423) is released from the lower part (422b) of the side body (422) and moves upward, the block guide shaft (425) can restrict the moving direction of the moving block (423). The moving block (423) can move from the lower part (422b) of the side body (422) to the upper part (422a) by the block guide shaft (425).

[0122] When the moving block (423) is supported or comes into contact with the upper part (422a) of the side body (422) by the rotation of the leveling shaft (425), the leveling shaft (425) may no longer rotate. The relative movement of the belt (32) and the belt fixer (43) with respect to the side body (422) may be terminated.

[0123] Accordingly, the moving blocks (423) located on both sides of the bar (40) can move up and down relative to the side body (422) of the bar (40) to finely adjust the position of the bar (40) with respect to the belt (32) and the belt fixer (43), and ensure the horizontality of the bar (40).

[0124]

[0125] Referring to FIG. 33 together with FIG. 17, when the bar (40) is moved up and down by the belt (32) while the horizontality of the bar (40) is secured, the shade film (45, see FIG. 17 and FIG. 18) can be maintained in a flat state. The shade film (45) that is maintained in a flat state can cover or open the display panel (11) from the rear of the display panel (11) without contacting the display panel (11) and / or the transparent panel (13) and while maintaining a gap therebetween.
