[0097]

[0098] Referring to FIG. 12, the holder (400) may be fixed to the rear or side of the frame (130). The frame (130) may include a pair of fixing holes (130h). The pair of fixing holes (130h) may be formed by penetrating the frame (130). When the first side part (411) and the second side part (412) of the holder (400) are pressed, a pair of connecting parts (443A, 443B) may be aligned with the pair of fixing holes (130h) formed in the frame (130). When the connecting parts (443A, 443B) of the holder (400) are inserted into the fixing holes (130h) of the frame (130), the force applied to the first side part (411) and the second side part (412) of the holder (400) is removed, and the holder (400) can be firmly fixed to the frame (130). Accordingly, the holder (400) can be easily assembled to the frame (130) by an automated process such as a robot.

[0099]

[0100] Referring to FIGS. 13 and 14, the source PCB (110PC) can be coupled to the holder (400). The source PCB (110PC) may be in the shape of an elongated plate. The source PCB (110PC) may be referred to as a source substrate (110PC). The source substrate (110PC) may be in the shape of an elongated plate. The upper long side (LS1) of the source substrate (110PC) can be inserted between the tension lever (430) and the upper line (401) of the receiving portion (400a) while being guided by the third part (433) of the tension lever (430). At this time, the source substrate (110PC) can be inserted into the first space (S1) as the tension lever (430) spreads away from the upper line (401) of the receiving portion (400a). The source board (110PC) can advance into the first space (S1) while in contact with the upper line (401) and / or the tension lever (430).

[0101] The lower long side (LS2) of the source substrate (110PC) can slide while in contact with the outer surface of the protruding lever (422) of the stopper (420). For example, the protruding lever (422) may have a rounded part (422a), and the rounded part (422a) may be formed at the end edge of the protruding lever (422). As another example, the protruding lever (422) may have an inclined part (422a), and the inclined part (422a) may be formed at the end edge of the protruding lever (422). The lower long side (LS2) of the source substrate (110PC), which was sliding while in contact with the outer surface of the protruding lever (422) of the stopper (420), can advance and come into contact with the upper step (403) after the upper long side (LS1) of the source substrate (110PC) is inserted into the first space (S1).

[0102] The upper long side (LS1) of the source substrate (110PC) in contact with the upper step (403) can move along the outer surface of the upper step (403) while spreading the tension lever (430) relative to the upper line (401). At this time, the section of the upper long side (LS1) of the source substrate (110PC) that moves can be adjusted by the multi-stage of the upper step (403).

[0103] When the lower long side (LS2) of the source substrate (110PC) passes the inclined portion (422a) of the protruding lever (422) and enters the second space (S2), the source substrate (110PC) may momentarily pivot at the boundary between the upper line (401) and the lower line (402), causing the source substrate (110PC) to tilt. Afterward, the source substrate (110PC) is pushed forward toward the second space (S2) by the force of the tension lever (430) attempting to return to its original state, and pivots at the boundary between the upper line (401) and the lower line (402), allowing the source substrate (110PC) to be aligned parallel to the upper line (401).

[0104] Accordingly, the source substrate (110PC) can be easily inserted into the holder (400) and can maintain a state of being firmly coupled to the holder (400) after insertion.

[0105]

[0106] Referring to FIG. 15, a member layer (MB) located on one side of a display panel (110, see FIG. 6) may be extended toward the rear or back side of the frame (130) while winding around one side of the frame (130). The member layer (MB) may be, for example, a COF or an FPCB.

Multiple holders (400A, 400B) may be located on the side or rear of the frame (130). Multiple holders (400A, 400B) may be located on the outer surface of the inclined portion (130DL3) of the frame (130). A source substrate (110PC) may be inserted into the holder (400).
