摘要： A conventional liquid crystal display comprises a number of components, so that a manufacturing cost cannot be reduced. Furthermore, a large-area substrate has problems in shipping. According to this invention, a liquid-crystal panel is prepared by forming individual optically functional films, a TFT device and a light-emitting device on a long thin film and then laminating the film by a transfer process. A base film to be a substrate in a liquid-crystal panel preferably has a thickness of 10 µm to 200 µm, a curvature radius of 40 mm or less as a measure of flexibility and a coefficient of thermal expansion of 50 ppm/°C or , less. Furthermore, it more preferably gives a variation of ±5 % or less in mechanical and optical properties to a thermal history at 200 °C.

摘要： An aromatic polymer containing aromatic polyamide structural units and aromatic carbohydrazide structural units at a specific ratio is disclosed. A film having a high Young's modulus, high elongation at break and low moisture absorption rate can be formed from such an aromatic polymer. Dehydration cyclization of a compound having a carbohydrazide structure can be conducted under mild conditions at low cost by causing the chemical reaction using a chemical which is selected from the acids and bases.

摘要： As a mobile display device, a translucent liquid crystal panel is a highly user-friendly display device capable of obtaining a clear image both in a dark place and a light place. However, it is expected to obtain a light-weight and robust display device of lower power consumption , i.e., having the advantages of the transparent type and reflection type liquid crystal panel. A liquid crystal panel having a back surface light emission light source includes: a liquid crystal element formed on a first basic body and sandwiching a liquid crystal element between a transparent first electrode and a transparent second electrode which are arranged to oppose each other; and a back surface light emission light source of the liquid crystal element formed on a second basic body and sandwiching a thin film planar light emitting element between an optically opaque third electrode and a transparent fourth electrode which are arranged to oppose each other. The third electrode is a reflection film arranged on the second basic body side and reflecting external light coming through the liquid crystal layer so as to introduce it into the liquid crystal layer. The fourth electrode is arranged to oppose to the second electrode. The insulation film sandwiched by the fourth electrode and the second electrode is a film formed continuously on the fourth electrode.

摘要： The present invention is an aromatic polyamide film, which is a laminated film consisting of at least two layers, comprising an aromatic polyamide and 0.1 wt% to 10 wt% of at least one or more different polymers, being contained at least in the outermost layer (layer A) of the film, subject to the condition that the following formulae are satisfied where d is the thickness of the layer A ( mu m); t, the circle equivalent diameter of the isles of the different polymer ( mu m); L, the major axis of the isles ( mu m); and s, the minor axis of the isles ( mu m). The aromatic polyamide film of the present invention is especially useful as a base film of a magnetic recording medium with high productivity since it is free from the wrinkling and weaving caused at the time of film winding and excellent in abrasion resistance on the film surface.
