<p>PURPOSE: By magnifying the angle which disperses the incident light by using the pattern layer in which the lenticular pattern is mixed or lays eggs it broadens the viewing angle and the optical film can rise the masking property. CONSTITUTION: A pattern layer(200) has the configured surface in which a plurality of lenticular patterns is formed into the continuous phase. In the pattern layer, the lenticular pattern(202) in which two lenticular patterns is overlapped of form and single lenticular pattern(201) is mixed. As to the base material layer, the thickness is about 400μm to 10. The base material layer(100) the sheet which is to the transparent resin which is used for the prism sheet or the prism film.</p> |
