Abstract

An apparatus for fabricating a liquid crystal display includes a vessel for containing a material for a spacer, an ink-jet head for jetting the material onto a plate and a light source for pre-curing the material by radiating light onto the material as the material is jetted from the ink-jet head. A method for fabricating a liquid crystal display includes the steps of aligning an ink-jet device relative to at least one of an upper plate and a lower plate, jetting a material for a spacer from the ink-jet device and pre-curing the material by irradiating the material with light while the material is jetted from the ink-system before the material impacts upon the at least one of the upper plate and a lower plate.

Claims (9)

1. An apparatus for fabricating a liquid crystal display, comprising:

a vessel for containing a material for a spacer;

an ink-jet head for jetting the material onto a plate of the liquid crystal display; and

a light source for pre-curing the material by radiating light onto the material while the material is jetted from the ink-jet head, the light source including a first light emitter on one side of the ink-jet head and a second light emitter on another side of the ink-jet head,

wherein light radiation ranges of the first light emitter and the second light emitter are overlapped with each other so that the first and second light emitters simultaneously radiate light onto same drops of the material from two respective different directions to procure the material prior to the material impacting upon the plate in order that a viscosity of the material increases.

2. The apparatus for fabricating a liquid crystal display as claimed in claim 1 , wherein the ink-jet head includes a nozzle positioned at a first distance from the plate for jetting the material from the vessel onto the plate.

3. The apparatus for fabricating a liquid crystal display as claimed in claim 2 , further comprising:

a protective cap provided on an end portion of the nozzle where the material jets out of the nozzle such that the end portion of the nozzle is shielded from said light source, the light source being at a second distance from the plate.

4. The apparatus for fabricating a liquid crystal display as claimed in claim 3 , wherein the first distance between the plate and the nozzle is less than the second distance between the light source and the plate.
