LIQUID CRYSTAL DROPPING DEVICE AND METHOD OF MANUFACTURING LIQUID CRYSTAL DISPLAY APPARATUS

摘要

Provided are: a liquid crystal dropping device capable of accurately dropping liquid crystal material while generation of foreign substances is suppressed; and a method of manufacturing a liquid crystal display apparatus capable of manufacturing a liquid crystal display apparatus with preferable display quality and high yield in which the occurrence of a display failure such as a luminous-dot failure is suppressed.;The liquid crystal dropping device 1 includes a liquid crystal bottle 2 which stores liquid crystal material 61, a three-way valve 3, a liquid crystal ejecting part 4, a nozzle 5 and a driving unit 7. The liquid crystal ejecting part 4 includes a syringe 41 with a bottomed cylindrical shape as well as a plunger 44 constituted by a slide part 42 which slides in the syringe 41 and a support 43 which has a bar-like shape and supports the slide part 42. The operation control part 8 reciprocates the plunger 44 before the liquid crystal material 61 is dropped from the nozzle 5, with a reciprocating distance shorter than a stroke for dropping the liquid crystal material.
