Abstract

A rubbing apparatus having a turning buffer for fabricating a liquid crystal display device is disclosed in the present invention. The turning buffer includes a first support having a first mother substrate mounted thereon, a first turning unit rotating the first support, a second support having a second mother substrate mounted thereon, and a second turning unit rotating the first support, wherein the first and second turning units are separated from one another.

Claims (20)

1. A turning buffer for a liquid crystal display panel, comprising:

a first support having a first mother substrate mounted thereon;

a first turning unit driving the first support to rotate the first mother substrate;

a second support having a second mother substrate mounted thereon; and

a second turning unit driving the second support to rotate the second mother substrate, wherein the first and second supports are separated from each other and the first mother substrate is separated from the second mother substrate.

2. The turning buffer of claim 1 , wherein each of the first and second supports comprises a plurality of tabs protruding from a surface of each of the first and second supports and are separated apart from one another.

3. The turning buffer of claim 1 , wherein the first and second turning units are operated independently.

4. The turning buffer of claim 1 , wherein the first and second turning units rotate the first and second supports by 180°.

5. A rubbing apparatus for fabricating a liquid crystal display panel, comprising:

first and second alignment layer forming units forming first and second alignment layers on surfaces of first and second mother substrates;

first and second rubbing units rubbing the first and second alignment layers; and

a separate body type turning buffer receiving the first and second mother substrates from the first and second alignment layer forming units through a first conveying unit to respectively transfer to the first and second rubbing units through a second conveying unit, wherein the separate body type turning buffer receives the first and second mother substrates rubbed by the first and second rubbing units through the second conveying unit to put the rubbed first and second mother substrates into a cassette simultaneously through the first conveying unit by rotating the rubbed first and second mother substrates independently.

6. The rubbing apparatus of claim 5 , wherein the separate body type turning buffer includes:

a first support having a first mother substrate mounted thereon;

a first turning unit rotating the first support;

a second support having a second mother substrate mounted thereon; and

a second turning unit rotating the second support, wherein the first and second turning units are separated from one another.

7. The rubbing apparatus of claim 5 , wherein each of the first and second supports comprises a plurality of tabs protruding from a surface of each of the first and second supports and are separated apart from one another.

8. The rubbing apparatus of claim 5 , wherein the first and second turning units are operated independently.

9. The rubbing apparatus of claim 5 , wherein the first and second turning units rotate the first and second supports by 180°.
