| 20090109375 | OPTICAL SHEET, METHOD OF MANUFACTURING THE SAME, AND DISPLAY APPARATUS - A method of manufacturing the optical sheet is provided. The method includes: a first step of heating a composition containing a liquid crystal monomer or liquid crystal prepolymer and a photopolymerization initiator at a temperature equal to or higher than a melting point of the liquid crystal monomer or liquid crystal prepolymer and pressing the composition in a state where the composition is held between a master including a plurality of solid structures disposed continuously in one surface and having shape anisotropy in the one surface and a light transmission film disposed so as to face the solid structures of the master. The method also includes a second step of irradiating the composition with ultraviolet rays at a temperature lower than a phase transmission temperature to an isotropic phase to polymerize the liquid crystal monomer or liquid crystal prepolymer and, after that, separating the light transmission film from the master. | 04-30-2009 |
| 20090147200 | VERTICAL ALIGNMENT FILM AND METHOD OF MANUFACTURING THEREOF, VERTICAL ALIGNMENT SUBSTRATE AND METHOD OF MANUFACTURING THEREOF, AND LIQUID CRYSTAL DISPLAY DEVICE - A highly reliable vertical alignment film for aligning display-use liquid crystal molecules in a direction slightly tilted from the substrate normal line direction and a method of manufacturing the vertical alignment film are provided. A layer composed of a liquid crystalline monomer that has a crystalline framework, and that has characteristics to align the crystalline framework vertically to an interface with a dissimilar material and polymerizable characteristics is formed on a transparent substrate. A magnetic field is applied thereto while the liquid crystal state is maintained, and thereby the liquid crystalline framework of the liquid crystalline monomer is aligned in a direction slightly tilted from the normal line direction of the substrate. In this state, the liquid crystalline monomer is polymerized, and a hardened layer formed from a complex composed of the unreacted liquid crystalline monomer and a liquid crystalline monomer polymer is formed as a vertical alignment film. | 06-11-2009 |
