Embodiment Construction

[0017] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0018] figure 1 is a perspective view of a nozzle assembly 100 for a liquid crystal dispensing device according to an embodiment of the present invention, and figure 2 yes figure 1 A perspective view of the resilient plate 120 of the nozzle assembly 100 is shown.

[0019] refer to figure 1 and figure 2 , the nozzle assembly 100 includes a nozzle 110 included in a liquid crystal dispensing device for forming a liquid crystal layer on a substrate by dispensing liquid crystal onto the substrate.

[0020] The nozzle 110 accommodates a predetermined amount of liquid crystal, and dispenses the liquid crystal onto the substrate while being relatively moved with respect to the substrate. The nozzle 110 has a space inside it, and includes a nozzle tip 111 at a lower end. Nozzle 110 receives liquid crystal...

Abstract

Provided is a nozzle assembly for a liquid crystal dispensing apparatus. The nozzle assembly includes: a nozzle receiving liquid crystal and dispensing the liquid crystal onto a substrate while respectively moving with respect to the substrate; and an elastic plate disposed at a passage through which the liquid crystal flows, in the nozzle, having at least one slit, and formed of an elastic material, wherein the elastic plate is elastically transformed to pass the liquid crystal through the elastic plate when a discharge pressure is applied to the liquid crystal, and the elastic plate is restored to its original shape and thus sucks liquid crystal drops remaining on a lower portion of the elastic plate back into an upper space of the elastic plate when no discharge pressure is applied to the liquid crystal.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 10-2006-0105058 filed on October 27, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to the manufacture of liquid crystal displays and, more particularly, to a nozzle assembly for use in a liquid crystal dispensing apparatus for dispensing liquid crystals onto a substrate. Background technique [0004] In general, a flat panel display (FPD) is a lighter and thinner image display device than a television or monitor using a cathode ray tube. Such flat panel displays include liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), organic light emitting diodes (OLEDs), and the like. [0005] The liquid crystal display displays desired images by respectively supplying data signals corresponding to image information to liquid crystal cells arrang...
