摘要： The polyamic acid of the invention can be obtained by the reaction of an acid anhydride component comprising pyromellitic anhydride and 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane with 2,2′-di-substituted-4,4′-diaminobiphenyls as a first aromatic diamine and any aromatic diamine component, as a second aromatic diamine, of 2,2-bis(4-aminophenoxyphenyl)propanes, 1,1-bis(4-(4-aminophenoxy)-3-t-butyl-6-methylphenyl)butane, 2,2-bis(3-amino-4-methylphenyl)hexafluoropropane and &agr;,&agr;′-bis(4-aminophenyl)diisopropylbenzenes in an organic solvent. The polyimide resin of the invention can be obtained by heating such a polyamic acid solution. In the production of a circuit board, by using a photosensitive polyamic acid having a sensitizer incorporated in such a polyamic acid solution, a patterned polyimide resin layer can be provided as an insulation layer on a metal foil.

摘要： There is provided a liquid crystal display panel having a high contrast ratio in a front direction. A liquid crystal panel of the present invention includes: a liquid crystal cell; a first polarizing plate placed on one side of the liquid crystal cell; and a second polarizing plate placed on another side of the liquid crystal cell. A transmittance (T1) of the first polarizing plate is higher than a transmittance (T2) of the second polarizing plate. Preferably, a difference (ΔT=T1−T2) between the transmittance (T1) of the first polarizing plate and the transmittance (T2) of the second polarizing plate is 0.1% to 6.0%.

摘要： It is an object of the present invention to provide a liquid crystal display panel having a high contrast ratio in a front direction.A liquid crystal panel according to an embodiment of the present invention includes: a liquid crystal cell; a first polarizing plate placed on one side of the liquid crystal cell; a second polarizing plate placed on the other side of the liquid crystal cell; and a retardation layer placed between the liquid crystal cell and the second polarizing plate. A refractive index ellipsoid of the retardation layer exhibits a relationship of n≧ny>nz; and a light transmittance (T2) of the second polarizing plate is larger than a light transmittance (T1) of the first polarizing plate. Such a liquid crystal panel has a remarkably higher contrast ratio in a front direction than that of a conventional liquid crystal panel (for example, a liquid crystal panel in which the light transmittances of two polarizing plates placed on both sides of a liquid crystal cell are the same), and shows excellent display properties.
