Abstract: A color liquid crystal display panel with improvements in brightness of display, viewing angle and workability which comprises a liquid crystal layer which is provided with two light-polarizing plates on opposite side as substrates. One of the light-polarizing plates is made, in the following order, from the light-polarizing layer, a color filter layer formed on the outside surface of a protective film layer, the protective film layer of non-rotary polarization polymer and a transparent conductive film layer formed on the inside surface of the protective film layer. The other light-polarizing plate is made in the following order, from the light-polarizing layer and a transparent conductive film layer.

Abstract: The present invention relates to a high-performance light-polarizing film assuming a neutral gray wherein are adsorbed and oriented, in a polymer film, (A) iodine as a main polarizing coloring matter and additionally (B) a dichroism dye having a absorption characteristics and polarization characteristics in the low wavelength region of visible light and showing, when adsorbed and oriented together with iodine in a polymer film, a direction of transition moment substantically identical with that of iodine and/or a dichroism dye having absorption characteristics and polarization characteristics in the high wavelength region of visible light and showing, when adsorbed and oriented together with iodine in a polymer film, a direction of transition moment substantially identical with that of iodine.

Abstract: A vibration-damping material consisting of two metal plates and a vibration-damping layer of thermoplastic resin interposed between the two metal plates, in which said thermoplastic resin has a percentage of wlongation at 20.degree. C. of 30% or more, preferably 50% or more, a peak temperature of dissipation factor (tan .delta.) in the range of -50.degree. C. to 130.degree. C., and a bonding strength toward the metal plates of 3 kg/cm or more as determined by 180.degree.-peeling test at 20.degree. C.

Abstract: Highly durable, light-polarizing film having neutral gray as well as high polarizing coefficient is provided. The film comprises a uniaxially stretched base polymer film of, for example, polyvinyl alcohol or derivatives thereof and at least two dichroism dyes adsorbed and orientated therein. The dichroism dyes are, for example, C.I. DIrect Yellow 12, C.I. Direct Black 17 and C.I. Direct Blue 202. The film is usable for display by liquid crystal. A boric-acid treatment is used to improve the polarization properties.
