Optical film, method of manufacturing the same, and display unit |
摘要 |
An optical film capable of improving luminance of a display unit, in which a viewing angle in the horizontal direction of emitted light of the display unit is wider than a viewing angle in the vertical direction and the emitted light of the display unit has a polarization component in the vertical direction viewable by polarized sunglasses, an illumination system including the same, and a display unit including the same are provided. The optical film includes a plurality of three-dimensional structures extending in one direction and arranged sequentially in a direction crossing the one direction. The three-dimensional structures contain a liquid crystalline polymer having orientation, and have refractive index anisotropy in which refractive index in the extending direction of the three-dimensional structures is smaller than refractive index in the direction crossing the extending direction of the three-dimensional structures. |
