| 20090238962 | METHOD OF PRODUCING OPTICAL FILM - In a method of producing an optical film including: a rubbing treatment step of rubbing a surface of a long plastic film F by a rubbing roll | 09-24-2009 |
| 20090296027 | ELLIPTICALLY POLARIZING PLATE AND IMAGE DISPLAY DEVICE USING THE SAME - Provided are an elliptically polarizing plate that is excellent in contrast in an oblique direction and has a broadband and a wide viewing angle, and an image display device using the elliptically polarizing plate. The elliptically polarizing plate of the present invention includes in order: a polarizer; a protective layer; a first birefringent layer having a refractive index profile of nz>nx=ny; a second birefringent layer that functions as a λ/2 plate; and a third birefringent layer that functions as a λ/4 plate. A ratio Rth | 12-03-2009 |
| 20100134737 | LIQUID CRYSTAL PANEL, LIQUID CRYSTAL DISPLAY APPARATUS USING THE PANEL, AND METHOD OF PRODUCING A LIQUID CRYSTAL PANEL - Provided are a liquid crystal panel and a liquid crystal display apparatus each of which: contributes to a reduction in thickness; and is excellent in optical characteristics, and a method of producing the liquid crystal panel with extremely high production efficiency. A liquid crystal panel of the present invention has a first polarizer, a first protective layer, a first optical compensation layer, a first negative C plate, a liquid crystal cell, a second negative C plate, a second optical compensation layer, a second protective layer, and a second polarizer in the stated order. The first optical compensation layer is arranged between the first protective layer and the first negative C plate to be in close contact with the first protective layer without using any adhesive. The second optical compensation layer is arranged between the second negative C plate and the second protective layer to be in close contact with the second protective layer without using any adhesive. The first and second optical compensation layers are each a coating layer functioning as a λ/4 plate, and each have a thickness of 0.3 to 3 μm. The first and second negative C plates are each a coating layer, and each have a thickness of 0.5 to 10 μm. | 06-03-2010 |
| 20110007248 | DEPOLARIZING FILM, PROCESS FOR PRODUCING THE SAME, AND LIQUID-CRYSTAL DISPLAY - Disclosed herein is a depolarizing film which is excellent in productivity and can have a large area. The depolarizing film is obtained by using birefringent very short fibers instead of inorganic birefringent crystals, such as calcite, for use in conventional depolarizing elements. | 01-13-2011 |
| 20110019279 | LIGHT DIFFUSING FILM AND PROCESS FOR PRODUCING THE LIGHT DIFFUSING FILM - A light diffusing film having superior productivity can be obtained by using very short fibers as a substitute for conventional spherical fine particles as light diffusing material. It is possible to mass-produce very short fibers at low cost, for example, by cutting fibers. Further, it is relatively easy to obtain very short fibers with a narrow fiber length distribution. The use of this makes it possible to carry out more highly sophisticated optical design of light diffusing films. | 01-27-2011 |
| 20110045177 | PROCESS FOR PRODUCTION OF LIGHT-DIFFUSING FILMS - There is provided a process for production of a light-diffusing film | 02-24-2011 |
