Abstract: An empty cell is produced by adhering an array substrate and a counterelectrode substrate with a sealant resin of a predetermined height. A mixture liquid comprising liquid crystal and a polymerizable photosetting resin is injected into the empty cell. Then, the cell is interposed between a flat rigid bench and a flat rigid plate, and the mixture liquid is heated to make it transparent. Then, the thickness of the mixture liquid is measured with an interferometer. If the measured thickness deviates from a predetermined range, the flat rigid plate is pressed until the measured thickness changes into the predetermined range. Then, the mixture liquid is irradiated to form a liquid crystal/resin composite layer. Then, the pressure is removed. Thus, a liquid crystal/resin composite layer of uniform thickness can be obtained.

Abstract: The present invention is intended to enable the change of the operating mode of an observation apparatus of a video system between a fluorescent observation mode and an ordinary observation mode and to enable the observation apparatus to reproduce a clear image for observation.

Abstract: A player initially sets the degree of difficulty of a display type game, and if desired, more than one player may participate with each player selecting an associated level of difficulty. First and second objects having different shapes, e.g. capsules and viruses, and different characteristics, e.g. different colors or shadings, are displayed in a predefined display area. First objects are generated based on random number data stored in a ROM and displayed as "falling" in a vertical direction across the predefined display area. Coordinate positions of the first objects on the display are changed by a player operating a controller. Second objects are displayed at arbitrary positions in the display area based on random number data. If a prescribed number of at least a portion of first objects and/or second objects having the same type characteristics are detected as being continuously aligned in a vertical or lateral direction, those continuously aligned objects are erased.
