Abstract: PURPOSE:To form such a thin film as not to support itself by forming the film of a thin-film supporting frame material via a shielding mask in the thin-film forming position on the substrate, then removing the mask, forming the thin-film material on the substrate to a prescribed thickness and dissolving away the substrate. CONSTITUTION:The thin film of Ti, Au is formed via a metallic mask member 2 on the substrate 1 consisting of an acrylic plate or the like which is easily soluble in an org. solvent, such as acetone, in a stage (a). The annular film which changes in the thickness in the peripheral part to a tapered shape is formed as the supporting frame 3 as shown in a stage (b). A vapor deposition source in a vacuum state is changed in this state to Be and the thin film 4 of the Be is formed on the supporting frame 3 and the substrate 1 at, for example, about 0.1mum thickness, over the entire surface without the mask in a stage (c).

Filed: 1982-03-30
Abstract: PURPOSE:To improve the transmission/cutoff ratio of light in a liquid crystal display markedly, by installing a louver for controlling light between a light emitting surface and a liquid crystal panel. CONSTITUTION:The light irradiated from the light emitting surface 3 of a light emitting device 2 passes through a louver 7, transmits through a liquid crystal panel 1 and arrives at an observation side 4.
