[0008] The lifting drive unit may include a motor; a lead screw rotated by the motor; and a block that is lifted along the lead screw.

[0009] The upper plate may include a block mount on which blocks are placed.

[0010] The linkage may include an upper link rotatably connected to the upper plate; a rotary link connected to the lower plate and rotatably connected to the base; and a lower link rotatably connected to each of the upper link and the rotary link.

[0011] The linkage may include an upper link, a lower link, and a guide link rotatably connected to each of the bases.

[0012] The guide link can be spaced apart from the rotation link in the vertical direction.

[0013] The lower plate may have a protruding connection.

[0014] A through hole may be formed in the rotating link.

[0015] The vehicle display device further includes a shaft.

[0016] The shaft can be positioned in the connection and can pass through the through hole.

[0017] The vehicle display device may further include a spring. The spring may be positioned on one of the connecting portion and the rotating link and may be in contact with the other of the connecting portion and the rotating link.

[0018] The supporting bar may have protrusions. The guide may have guide rails formed to guide the protrusions.

[0019] Multiple supporting bars may be provided on the front of the flexible display.

[0035] Additionally, the flexible display can be flattened and the top height of the flexible display can be increased, allowing the flexible display to provide a large screen.

[0036] Additionally, since the upper plate is raised and lowered by the motor and linkage and the lower plate is rotated, the number of parts and weight can be minimized.

[0037] Additionally, the guide guides the support bar so that the flexible display can bend smoothly.

[0038] Additionally, the support bar can be supported by the support bracket to minimize the pressure on the flexible display.

[0039] In addition, the rotary link is connected to a shaft placed on the lower plate so that the rotary link can slide along the shaft, and the spring can elastically support the rotary link, thereby minimizing the influence of vibrations, etc.
