20090033834 | LIQUID CRYSTAL LAYER FORMING INK COMPOSITION, AND OPTICAL FILM, POLARIZING FILM AND LIQUID CRYSTAL DISPLAY PRODUCED WITH THE INK COMPOSITION - An ink composition capable of forming a liquid crystal layer even on a base material with no alignment treatment applied; and an optical film, a polarizing film and a liquid crystal display produced using the ink composition. The liquid crystal layer forming ink composition has a liquid crystalline molecular material, an organic solvent for dissolving or dispersing the molecular material, and an alcohols solvent. By applying the ink composition on a base material, drying, and aligning the liquid crystal molecule material, an optical film with a liquid crystal layer formed can be obtained. Since the alcohols solvent is contained in the liquid crystal composition, the liquid crystalline molecular material is in a state horizontally aligned on the base material, and the optical film can have a high transparency. | 02-05-2009 |
20110134469 | IMAGE FORMING APPARATUS, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM - When a preview image is displayed, an area on which a certain finishing process is executed is automatically enlarged and displayed. A control method for controlling an image forming apparatus including a display unit for previewing print results obtained by printing print information to be printed, the control method comprising: determining a preview position and a preview magnification rate of the print results to be displayed on the display unit, based on a post-processing setting for the print information; and controlling a preview of the print results to be displayed on the display unit, based on the determined preview position and preview magnification rate. | 06-09-2011 |
20130093982 | LIQUID CRYSTAL DISPLAY DEVICE AND POLARIZER PROTECTIVE FILM - The present invention aims to provide a liquid crystal display device highly suppressing occurrence of rainbow interference pattern in displayed images. The present invention is a liquid crystal display device including: a back light source, a liquid crystal cell, a color filter, a polarizer, and a polarizer protective film arranged in the stated order, wherein the polarizer protective film has a retardation of not less than 6000 nm, and a difference (nx−ny) of not less than 0.05 between a refractive index (nx) in a slow axis direction that is a highest refractive index direction and a refractive index (ny) in a fast axis direction that is orthogonal to the slow axis direction, and an absorption axis of the polarizer and the slow axis of the polarizer protective film are arranged to form an angle within a range of 0°±30° or 90°±30°. | 04-18-2013 |
20130279155 | ANTIGLARE FILM, POLARIZER AND IMAGE DISPLAY DEVICE - Provided is an antiglare film having a hard coat property, capable of highly suppressing generation of a rainbow interference pattern and interference fringes in display images, preventing white muddiness and scintillation of a display screen, while giving high contrast in a bright room and a dark room. The antiglare film includes an antiglare layer having an uneven form on its surface and formed on one face of a transparent substrate having an in-plane birefringence and a retardation of 3000 nm or higher. The antiglare layer contains silica fine particles, organic fine particles, and a binder resin. The silica particles include particles forming agglomerates to be contained coarsely and densely in the antiglare layer. The agglomerates are distributed densely around the organic fine particles, and some agglomerates adhere to surfaces of the organic particles and/or some silica particles are impregnated in the inside of the organic particles. | 10-24-2013 |
20140184994 | OPTICAL LAYERED BODY, POLARIZER, METHOD FOR PRODUCING POLARIZER, IMAGE DISPLAY DEVICE, METHOD FOR PRODUCING IMAGE DISPLAY DEVICE, AND METHOD FOR IMPROVING VISIBILITY OF IMAGE DISPLAY DEVICE - The present invention provides a method for improving visibility of an image display device which is capable of providing an image display device excellent in anti-reflection properties and bright-field contrast even using an optical layered body including a light-transmitting substrate having in-plane birefringence, such as a polyester film.
