A method of fabricating a liquid crystal display device, including forming a common electrode on one substrate; forming gate and data bus lines, a thin-film transistor, a pixel electrode, and a Cs bus line on another substrate. For this purpose, a destination floor indication device installed in a hall or car of the elevator is includes an indication part that indicates registered destination floors to elevator users, and indication contents of this indication part are controlled by an indication control part. The disassembly-capable mount includes a pair of stringers each being removably disposable in a respective one of the receipt devices of the recliner surface material and a pair of spacers releasably securable with the stringers. The locking branches are housed in the slots provided in the rotary spindle to lock in rotation the spring relative to the rotary spindle, the spring being moreover maintained axially between the push-button and a shoulder of the rotary spindle. The device improves the precision and safety of its handling, and offers the practitioner several aspiration alternatives while maintaining separation of the internal and external patient environments.
