Claims
- 1. A photosensitive resin plate for printing an orientation layer on a liquid crystal display panel, comprising:a photosensitive resin body; at least one polyimide(PI) pattern portion formed on a surface of said body, said PI pattern portion including a plurality of projections having a first hardness; and at least one polyimide (PI) pattern edge portion positioned proximate said PI pattern portion on the surface of said body, said PI pattern edge portion comprising a plurality of projections having a second hardness, wherein said second hardness is greater than said first hardness.
- 2. A photosensitive resin plate according to claim 1, wherein said PI pattern portion corresponds to an effective screen area of an LCD panel, and wherein said PI pattern edge portion corresponds to a non-effective screen area of said LCD panel.
- 3. A photosensitive resin plate according to claim 2, wherein said at least one PI pattern portion and PI pattern edge portion are each a plurality of portions, and wherein each of said PI pattern edge portions corresponds to one PI pattern portion to define a PI pattern set, and wherein each PI pattern set is spaced apart from the next adjacent PI pattern set.
- 4. A photosensitive resin plate according to claim 3, further comprising at least one dummy pattern having a series of cells formed therein disposed on said body, and wherein said dummy pattern is spaced apart from said PI pattern edge portion opposite said PI pattern portion.
- 5. A photosensitive resin plate according to claim 4, wherein said at least one dummy pattern is arranged on said body such that it defines a barrier between adjacent PI pattern sets.
- 6. A photosensitive resin plate according to claim 5, wherein said at least one dummy pattern is a plurality of dummy patterns, each of which is arranged on said body such that it surrounds a corresponding one of said PI pattern sets.
- 7. A photosensitive resin plate according to claim 6, wherein said dummy pattern is configured in a rectangular or square shape on said body.
- 8. A photosensitive resin plate according to claim 7, wherein each of said dummy patterns has a contiguous boundary, including contiguous first and second opposing sides and a top and bottom, and wherein adjacent dummy patterns meet along portions of said boundaries.
- 9. A photosensitive resin plate according to claim 7, wherein at least one laterally adjacent pair of dummy patterns meet along one side.
- 10. A photosensitive resin plate according to claim 1, wherein said PI pattern edge portion is configured to abut and enclose said polyimide pattern portion.
- 11. A photosensitive resin plate according to claim 1, wherein said plurality of projections of said pattern portion and said pattern edge portion are arranged in a repeating pattern having a predetermined repetition interval.
- 12. A photosensitive resin plate according to claim 1, wherein said photosensitive resin is polybutadiene.
- 13. A photosensitive resin plate according to claim 12, wherein said polybutadiene of said resin body is surface-coated with benzophenone.
- 14. A photosensitive resin plate according to claim 1, wherein said PI pattern edge portion projections comprise a plurality of tapered projections.
- 15. A photosensitive resin plate according to claim 1, wherein said PI pattern portion is configured as a rectangular shaped surface pattern on said body and includes a series of projections and cells, and wherein said PI pattern edge portion encloses the perimeter of said rectangular shaped surface pattern.
- 16. A photosensitive resin plate according to claim 1, wherein said second hardness is selected to be resistant to damage attributed to contact with an underlying glass surface during flexographic printing of the glass surface.
- 17. A photosensitive resin plate for printing an orientation layer on a liquid crystal display panel, comprising:a photosensitive resin body; at least one polyimide (PI) pattern portion formed on a surface of said body, said PI pattern portion including a plurality of projections having a first hardness; and at least one polyimide (PI) pattern edge portion positioned proximate said PI pattern portion on the surface of said body, said PI pattern edge portion comprising a plurality of projections having a second hardness, wherein said second hardness is greater than said first hardness, wherein said PI pattern portion corresponds to an effective screen area of an LCD panel, and wherein said PI pattern edge portion corresponds to a non-effective screen area of said LCD panel, wherein said at least one PI pattern portion and PI pattern edge portion are each a plurality of portions, and wherein each of said PI pattern edge portions corresponds to one PI pattern portion to define a PI pattern set, and wherein each PI pattern set is spaced apart from the next adjacent PI pattern set, and wherein said photosensitive resin plate further comprises at least one dummy pattern positioned between at least one of said PI pattern sets, said dummy pattern including a plurality of projections thereon.
- 18. A photosensitive resin plate according to claim wherein said at least one dummy pattern is a plurality of dummy patterns, and wherein said dummy patterns are spaced apart from and surround each of said PI pattern sets.
