Polarization film
View Patent ↗A polarization film comprising at least a polarization layer subject to a laminating treatment along a predetermined laminating direction, wherein the polarization film further comprises an adhesive layer that is capable of being affixed onto a base and has a maximal shrinkage resistance in the laminating direction of the polarization layer.
1. A polarization film comprising at least a polarization layer subject to a laminating treatment along a predetermined laminating direction, wherein the polarization film further comprises an adhesive layer that is capable of being affixed onto a base and has a maximal shrinkage resistance in the laminating direction of the polarization layer; and
wherein the adhesive layer comprises a plurality of adhesive regions and a plurality of non-adhesive regions, and the adhesive regions and the non-adhesive regions are arranged alternatively along the laminating direction of the polarization layer.
2. The polarization film of claim 1 , wherein the adhesive layer has a minimal shrink resistance in a direction perpendicular to the laminating direction of the polarization layer.
3. The polarization film of claim 1 , wherein the non-adhesive regions are elongated holes extending along a direction perpendicular to the laminating direction of the polarization layer.
4. The polarization film of claim 3 , wherein the length of the elongated holes decreases gradually along the laminating direction of the polarization layer.
5. The polarization film of claim 1 , wherein the non-adhesive regions are hole groups that are aligned along a direction perpendicular to the laminating direction of the polarization layer.
6. The polarization film of claim 5 , wherein the number of the holes in the hole groups decreases gradually along the laminating direction of the polarization layer, and the alternating times for the adhesive regions and the non-adhesive regions decrease gradually along the direction perpendicular to the laminating direction of the polarization layer.
7. The polarization film of claim 1 , further comprising a surface treatment layer, a first support layer, and a second support layer, wherein the polarization layer is interposed between the first support layer and the second support layer.
8. A polarization film for a liquid crystal display (LCD) panel comprising at least an adhesive layer that is capable of being affixed onto the LCD panel and a polarization layer subject to a laminating treatment along a predetermined laminating direction,
wherein the adhesive layer comprises a plurality of adhesive regions and a plurality of non-adhesive regions, and the adhesive regions and the non-adhesive regions are arranged along the laminating direction alternatively.
9. The polarization film for a LCD panel of claim 8 , wherein the non-adhesive regions are elongated holes extending along a direction perpendicular to the laminating direction.
10. The polarization film for a LCD panel of claim 9 , wherein the length of the elongated holes decreases along the laminating direction of the polarization layer.
11. The polarization film for a LCD panel of claim 8 , wherein the non-adhesive regions are hole groups that are arranged along a direction perpendicular to the laminating direction.
12. The polarization film for a LCD panel of claim 11 , wherein the number of the holes in the hole groups decreases gradually along the laminating direction of the polarization layer, and the alternating times for the adhesive regions and the non-adhesive regions decrease along the direction perpendicular to the laminating direction of the polarization layer.
13. The polarization film for a LCD panel of claim 8 , further comprising a surface treatment layer, a first support layer, and a second support layer, wherein the polarization layer is interposed between the first support layer and the second support layer.
