US 8018654 B2Abstract
13. The optical sheet of claim 12, wherein a thickness of the base part ranges from 5%˜50% of a height of a peak of the projection.
20. The liquid crystal display device of claim 15, wherein a thickness of the base part ranges from about 5%˜50% of height of a peak of the projection. Description
The projection as shown in FIG. 11 may comprise a base part 128 c. The base part 128 c disposed on the first primer layer 130, wherein a thickness D of the base part 128 c ranges from about 5%˜50% of the height between the peak 128 a and valley 128 b. The projection as shown in FIG. 12 may comprise a plurality of beads 140 and a base part 129 c. The base part 129 c disposed on the first primer layer 130, wherein a thickness D of the base part 128 c ranges from about 5%˜50% of the height between the peak 129 a and valley 129 b. As shown in FIG. 13 to FIG. 16, an optical sheet according to a second exemplary embodiment of the present invention may comprise a base film 210. In addition, the optical sheet may comprise a projection 220, 221, 223, 224 disposed on one surface of the base film 210. Also, the optical sheet may comprise a first primer layer 230 a positioned between the base film 210 and the projection 220. The optical sheet may comprise a second primer layer 230 b disposed on the other surface of the base film 210. A refractive index of the first primer layer 230 a and that of the second primer layer 230 b may be different.
The projection 221 as shown in FIG. 14 may comprise a base part 221 c. The base part 221 c disposed on the first primer layer 230 a, wherein a thickness D of the base part 221 c ranges from about 5%˜50% of the height between the peak 221 a and valley 221 b. The projection 224 as shown in FIG. 16 may comprise a plurality of beads 240 and a base part 224 c. The base part 224 c disposed on the first primer layer 230 a, wherein a thickness D of the base part 224 c ranges from about 5%˜50% of the height between the peak 224 a and valley 224 b. The first and second primer layers 230 a and 230 b may be selectively used to improve adhesion, an external appearance, and optoelectronic characteristics, and may be made of acryl, ester, urethane, etc., but not limited thereto.
