Benefits of technology
The present invention provides an apparatus for forming a liquid crystal fence that can reduce damage to LCD panels. The apparatus includes a base body, an assembled substrate, a light supply unit, and an exposure mask. The assembled substrate is mounted on the base body and divided into a liquid crystal receiving area and a liquid crystal fence area surrounding it. The assembled substrate also includes two substrates and a spacer disposed between them, formed at the liquid crystal fence area and cured by an exposure to a light. The light supply unit supplies light to the assembled substrate, and the exposure mask is placed on the assembled substrate to change the spacer into a liquid crystal fence by selectively supplying light to it. This invention prevents deterioration of the liquid crystal and alignment layer and reduces the temperature increase caused by the light supply unit.
Problems solved by technology
As a result, an alignment layer of the TFT substrate may be damaged and the liquid crystal may be deteriorated.

Embodiment Construction
[0031]FIG. 1 is a schematic view showing an apparatus for forming a liquid crystal fence according to an exemplary embodiment of the present invention. FIG. 2 is a plan view showing an assembled substrate shown in FIG. 1.
[0032] Referring to FIGS. 1 and 2, an apparatus 500 for forming a liquid crystal fence includes a base body 100, a light supply unit 200 and an exposure mask 300.
[0033] The base body 100 is provided with an assembled substrate 400. The assembled substrate 400 mounted on the base body 100 includes two substrates 410 and 420 and a spacer 450 disposed between the two substrates 410 and 420. The assembled substrate 400 is divided into at least one liquid crystal receiving area 430 and a liquid crystal fence area 440 surrounding the liquid crystal receiving area 430. The spacer 450 is formed at the liquid crystal fence area 440 and comprises a light-curable material cured by an exposure to a light 201.
[0034] As shown in FIG. 1, the light supply unit 200 is disposed on...

Abstract
In a backlight assembly, an assembled substrate on which a spacer including a light-curable material is formed is disposed on a base body and a light supply unit disposed on the base body provides a light to the assembled substrate so as to cure the spacer. An exposure mask formed with an opening is positioned at a path through which the light is supplied so as to selectively supply the light to the spacer of the assembled substrate.
Description
CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of application Ser. No. 10 / 454,487, filed Jun. 5, 2003, which claims priority to Korean Patent Application No. 2002-69468, filed Nov. 9, 2002, the disclosure of which in its entirety is incorporated by reference herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an apparatus for forming a liquid crystal fence, and more particularly to an apparatus for forming a liquid crystal fence disposed between a TFT (Thin Film Transistor) substrate and a color filter substrate so as to provide a space for receiving liquid crystal and to couple the TFT substrate to the color filter substrate. [0004] 2. Description of the Related Art [0005] In an LCD (Liquid Crystal Display) panel, liquid crystal is interposed between a TFT substrate and a color filter substrate manufactured through fabricating processes different from each other. [0006] An alignment of the li...
