Abstract
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 deviceincludes a liquid crystal bottlewhich stores liquid crystal material, a three-way valve, a liquid crystal ejecting part, a nozzleand a driving unit. The liquid crystal ejecting partincludes a syringewith a bottomed cylindrical shape as well as a plungerconstituted by a slide partwhich slides in the syringeand a supportwhich has a bar-like shape and supports the slide part. The operation control partreciprocates the plungerbefore the liquid crystal materialis dropped from the nozzle, with a reciprocating distance shorter than a stroke for dropping the liquid crystal material.
