    摘要： A thin film transistor where source and drain electrodes are film laminates including at least two layers. A first layer film of the laminate, which is formed to a thickness of 10 to 700 .ANG. is in ohmic contact with underlying semiconductor film. A second layer film, formed on the first layer film has a thickness of more than about 2000 .ANG. and is a material having a sufficient adhesion strength even when formed at a temperature which is less than the temperature corresponding to the materials vapor pressure. Further, the materials used for the source and drain electrodes can be formed into thin films by ordinary sputtering or vacuum deposition techniques, low in cost, and readily available. A thin film transistor according to the present invention is formed on a substrate by the steps of: forming a gate electrode on the substrate; oxidizing the gate electrode to form a gate insulating film, the gate electrode and the gate insulating film forming a step; forming a thin film semiconductor on the gate insulating film; forming a first layer film portion of a source and drain electrode film laminate on the thin film semiconductor and in ohmic contact with the thin film semiconductor; and forming a second layer film portion of the source and drain electrode film laminate, the second layer film being an adhesion layer, convering the first layer film, and having a sufficient thickness to provide a continuous film across the step.

    摘要： The lighting device is equipped with a light guide having a linear Fresnel reflection surface consisting of steps of continuously alternating reflecting surfaces having two different reflection angles. A light source is installed at one end of the light guide of the above construction so that the light from the light source is emitted from the irradiation surface of the light guide after being reflected by the linear Fresnel reflection surface.

    摘要： A nematic-phase liquid crystal material is sandwiched between two opposing parallel plates at least one of which is transparent. The two parallel plates are respectively coated with transparent electrode films having parallel micro-groove structures at the respective inner surfaces in contact with the nematic-phase liquid crystal material established by unidirectional rubbing. In particular, an additional or second micro-groove structure is further provided for said fist-named micro-groove structure which has an asymmetric or anisotropic profile along the longitudinal axes of the respective micro-grooves within the first micro-groove structure, preferably of a substantially saw-tooth profile. This combination results in a surface anisotropy in solid geometry rather than in plane geometry in the interfacial surfaces. The surface anisotropies in the two interfacial surfaces should be established in a complemental relationship in a manner to attain uniform aligment of liquid crystal molecules and hence to reduce free energy due to the liquid crystal molecules, therefore, non-uniformity of display is alleviated.

    摘要： In a multi-layer matrix type liquid crystal display panel having a stack of liquid crystal display cells and matrix electrodes provided for respective ones of the liquid crystal display cells, the supports of the respective liquid crystal display cells are piled sequentially, one on top of the other, with a first dimension sequentially longer and a second dimension sequentially shorter, thereby allowing enough room on all sides for electrode connections. A rigid circuit board has terminals which are located in a complementary fashion with respect to the terminals of the display panel. The opposing terminals of the display panel and the circuit board are connected through a flexible sheet.
