    摘要: The present invention relates to a dye-containing light-polarizing film wherein a disazo dye represented by the formula (I) is used: ##STR1## wherein Me represents a transition metal, being copper, nickel, zinc or iron, R represents a 1-naphthol or 2-naphthol residue which is bonded to azo group at the position adjacent to its hydroxyl group forming a complex bond together with the transition metal and which may have a substituent such as a sulfonic acid, sulfonamide, amino, acylamino or arylamino group or a hydroxyl group not adjacent to the azo group, X and Y represent a hydrogen atom, a C.sub.1 -C.sub.4 alkyl, lower alkoxy, carboxylic acid, sulfonic acid, sulfonamide, sulfonalkylamide, amino, acrylamino or nitro group or a halogen atom, and Z represents a hydrogen atom or a C.sub.1 -C.sub.4 alkyl or lower alkoxy group, said formula (I) having from 1 to 3 sulfonic acid groups.Said dye-containing light-polarizing film, as compared with the conventional ones, not only exhibits a high durability, but also has excellent polarization performance enough to be comparable to the light-polarizing films in which iodine is used. Consequently, said dye-containing light-polarizing film is effectively used for use in displays in which liquid crystals are used and optical instruments including CRT filters.

    摘要: A phase retarder obtained by uniaxially stretching a thermoplastic resin film, whose retardation value ranges from 30 to 1200 nm and whose color difference .DELTA.E* is not more than 30 as defined with the phase retarder being set between crossed polarizers in such a manner that the optical axis thereof makes an angle of 45.degree. with respect to the planes of polarization of the polarizers, and a liquid crystal display using the phase retarder are disclosed. The phase retarder has a fixed optical axis, a retardation value suited for new optical uses including liquid crystal displays, and freedom from optical color unevenness. The liquid crystal display using the phase retarder exhibits markedly improved image quality.

    摘要: A phase retarder and a process for producing the same are disclosed. The phase retarder is obtained by shrinking a uniaxially stretched thermoplastic high polymer film in the direction perpendicular to the stretching direction at a lengthwise shrink of at least 2%. The phase retarder has a ratio of a retardation value (R.sub.30) measured on the phase retarder being inclined at a angle of 30.degree. with respect to the orientation axis as an axis of rotation to a retardation value (R.sub.0) measured on the phase retarder being held horizontally, each measured with a polarizing microscope, (R.sub.30 /R.sub.0) of not more than 1.10, and preferably not more than 1.07. A liquid crystal display fitted with the phase retarder exhibits broad viewing angle characteristics while achieving a satisfactory B/W display level.

    摘要: The present invention provides a transflective film comprising a polymer film having an in-plane phase retardation value of about 30 nm or less and a transflective layer made of an inorganic compound, wherein the transflective layer is coated on the polymer film and a reflectance of the transflective film is from about 10% to about 95%. When an absorption-type polarizer is laminated to the polymer film side of the transflective film, a transflective polarizer is provided. When a reflection-type polarizer is laminated to the transflective layer side of the transflective film, a transflective polarizer used in a system improving luminance is provided. Using these transflective polarizers, a polarizing light source device and a transflective liquid crystal display device are provided.
