20090162542 | Optical element obtained by homeotropically orienting liquid crystal molecule, member for liquid crystal display device using the same, and liquid crystal display device - An object of the present invention is to provide an optical element which can suppress a production cost, has good heat resistance, uniformly maintains the fixed orientation of a liquid crystal polymer in a wide temperature range, shows a low haze with reliability, and can maintain desired birefringence property with reliability. The present invention relates to an optical element formed by forming, on an upper surface of a base material having light transmittance, at least a birefringence layer having a structure obtained by fixing liquid crystal monomers each having a polymerizable group at a terminal thereof in a state where the monomers are homeotropically oriented, and by removing an additive layer formed on the upper surface of the birefringence layer. | 06-25-2009 |
20090185121 | Display base having a retardation control function with a high voltage holding ratio - A display board with a retardation control function has a retardation control layer containing liquid crystalline polymers with a fixed orientation, and a liquid crystal layer. The display board has a voltage holding ratio of 90% or higher after a forced impurity extraction is performed on the display board with the retardation control layer in contact with the liquid crystal layer, and application of a voltage to the liquid crystal layer. The display board is capable of providing a high quality display while preventing a drop in the voltage holding ratio attributed to impurities mixed into the liquid crystal layer, and thus preventing the occurrence of display defects, such as flickering. | 07-23-2009 |

20160086774 | PLASMA PROCESSING APPARATUS, PLASMA PROCESSING METHOD, AND METHOD FOR MANUFACTURING ELECTRONIC DEVICE - In an inductively-coupled plasma torch unit, a coil, a first ceramic block, and a second ceramic block are arranged, parallel to one another, and an elongated chamber has an annular shape. Plasma generated inside the chamber is ejected toward a substrate through an opening portion in the chamber. The substrate is processed by relatively moving the elongated chamber and the substrate in a direction perpendicular to a longitudinal direction of the opening portion. A rotating ceramic pipe having a cylindrical shape is provided so as to cause a refrigerant to flow into a cavity formed inside the ceramic pipe. Accordingly, it becomes possible to apply greater high-frequency power, thereby enabling fast plasma processing. | 03-24-2016 |
