| 20080213508 | COLOR PURITY IMPROVING SHEET, OPTICAL APPARATUS, IMAGE DISPLAY, AND LIQUID CRYSTAL DISPLAY - The present invention provides a highly practicable color purity improving sheet that while preventing unevenness in color and brightness from occurring, allows light with an improved color purity to be used for an image display efficiently and can improve color reproducibility of the image display. The color purity improving sheet includes a light-emitting layer which improves the purity of a color in a target wavelength range by absorbing light in a specific wavelength range other than the target wavelength range and converts the absorbed light to emitted light in the target wavelength range. The surface of the light-emitting layer on at least the light outgoing side is roughened so as to have an arithmetic average surface roughness Ra defined in JIS B 0601 (1994 version) in the range of 0.1 to 100 μm. | 09-04-2008 |
| 20100039591 | CROSSLINKED PRODUCT, COLOR CORRECTION FILTER, OPTICAL ELEMENT, IMAGE DISPLAY, AND LIQUID CRYSTAL DISPLAY - A crosslinked product with excellent durability is provided that can remove intermediate colors of light while preventing brightness from deteriorating and thereby can improve color tone representation. The crosslinked product of the present invention includes a J aggregate of a dye and is characterized in that the dye is at least one dye selected from the group consisting of cyanine, merocyanine, squarylium, and porphyrin, the J aggregate of the dye is formed in a matrix resin, and the matrix resin has been crosslinked. | 02-18-2010 |

| 20100307587 | METHODS FOR CONTROLLING OPTICAL PROPERTY OF WAVELENGTH CONVERSION SHEET AND FOR PRODUCING WAVELENGTH CONVERSION SHEET, WAVELENGTH CONVERSION SHEET FOR CADMIUM TELLURIDE SOLAR CELL, AND CADMIUM TELLURIDE SOLAR CELL - The present invention provides a method for controlling an optical property of a wavelength conversion sheet. The method is a method for controlling an optical property of a wavelength conversion sheet that contains a transparent resin and a phosphor and achieves wavelength conversion by absorbing light in a specific wavelength range other than a target wavelength range and emitting light in a target wavelength range, wherein the phosphor contains a phosphor having a perylene skeleton, and a stokes shift of the wavelength conversion sheet is controlled by adjusting a concentration of the phosphor having a perylene skeleton to the transparent resin in a range of 0.5% to 3.5% by weight. | 12-09-2010 |
