Method and apparatus of aligning alignment layer, and method of manufacturing liquid crystal display using the same

1. An apparatus of aligning an alignment layer of a panel, the apparatus comprising:

a light source generating a light;

a stage receiving a substrate having the alignment layer provided thereon, the alignment layer comprising a plurality of alignment regions;

a data processor loading data identifying positions of the alignment regions relative to the alignment layer and generating a control signal for controlling the light based on the loaded data identifying the positions of the alignment regions;

a plurality of first optical heads, each of which is inclined in a first direction, receiving the control signal, controlling the light and selectively supplying the light to a first set of the alignment regions of the alignment layer at a first angle of incidence, and

a plurality of second optical heads, each of which is inclined in a second direction different from the first direction, receiving the control signal, controlling the light and selectively supplying the light to a second set of the alignment regions of the alignment layer at a second angle of incidence different from the first angle of incidence.

2. The apparatus of claim 1 , wherein the pluralities of first and second optical heads are configured to supply the light at an incline with respect to a line normal to a top surface of the alignment layer.

3. The apparatus of claim 2 , wherein the first direction is an opposite direction from the second direction.

4. The apparatus of claim 3 , wherein the apparatus further comprises:

a plurality of third optical heads, each of which is inclined in a third direction, receiving the control signal, controlling the light and selectively supplying the light to a third set of the alignment regions of the alignment layer at a third angle of incidence; and

a plurality of fourth optical heads, each of which is inclined in a fourth direction different from the third direction, receiving the control signal, controlling the light and selectively supplying the light to a fourth set of the alignment regions of the alignment layer at a fourth angle of incidence different from the first, second, and third angles of incidence.

5. The apparatus of claim 4 , wherein the third direction is an opposite direction from the fourth direction.

6. The apparatus of claim 2 , wherein the optical heads each comprise a micromirror apparatus comprising a plurality of micromirrors selectively supplying the light from the light source to the alignment layer.

7. The apparatus of claim 6 , wherein the pluralities of first and second optical heads each further comprise a multi-focal lens provided at a lower portion of the micromirror apparatus and adjusting a focus of the light supplied to the alignment layer.

8. The apparatus of claim 2 , wherein the pluralities of first and second optical heads each comprise a lens apparatus comprising a fixed lens receiving the light from the light source and a movable lens receiving the light from the fixed lens and supplying the light to the alignment regions of the alignment layer.

9. The apparatus of claim 8 , wherein the pluralities of first and second optical heads each further comprise a multi-focal lens provided at a lower portion of the lens apparatus and adjusting a focus of the light supplied to the alignment layer.

10. The apparatus of claim 1 , wherein the light comprises a linearly-polarized ultraviolet (UV) light.
