Abstract

A method of manufacturing a liquid crystal display panel is provided, which includes: coating a negative organic photoresist on a substrate; performing divisional light exposure with a plurality of shots including first and second shots adjacent to each other; and developing the photoresist to form a light blocking member having a plurality of openings, wherein the first and the second shots have a boundary crossing the openings.

Claims (20)

1. A method of manufacturing a liquid crystal display panel, the method comprising:

coating a negative organic photoresist on a substrate;

performing divisional light exposure with a plurality of shots including first and second shots adjacent to each other; and

developing the photoresist to form a light blocking member having a plurality of openings,

wherein the first and the second shots have a boundary crossing the openings.

2. The method of claim 1 , further comprising:

preparing a stitch area that is disposed near the boundary of the first and the second shots and includes a plurality of stitch cells, each stitch cell being light-exposed in one of the first and the second shots and light-blocked in the other of the first and the second shots.

3. The method of claim 2 , wherein the number of the light-exposed stitch cells or the light-blocked stitch cells is gradually decreasing or increasing along a direction from the first shot to the second shot.

4. The method of claim 3 , wherein each of the stitch cells includes a pixel area, a plurality of pixel areas, or a portion of a pixel area.

5. The method of claim 3 , wherein the stitch cells have boundaries crossing the openings.

6. The method of claim 5 , wherein each of the stitch cells has boundaries crossing at least two of the openings.

7. A method of manufacturing a liquid crystal display panel by a divisional exposure with a plurality of shots including first and second shots adjacent to each other, the method comprising:

coating a negative organic photoresist on a substrate;

preparing a stitch area that is disposed near the boundary of the first and the second shots and includes a plurality of stitch cells;

performing the first and the second shots in sequence; and

developing the photoresist to form a light blocking member having a plurality of openings,

wherein each stitch cell is light-exposed in one of the first and the second shots and light-blocked in the other of the first and the second shots, and the stitch cells have boundaries crossing the openings.

8. The method of claim 7 , wherein the number of the light-exposed stitch cells or the light-blocked stitch cells is gradually decreasing or increasing along a direction from the first shot to the second shot.

9. The method of claim 8 , wherein each of the stitch cells includes a pixel area, a plurality of pixel areas, or a portion of a pixel area.

10. The method of claim 7 , wherein each of the stitch cells has boundaries crossing at least two of the openings.
