    • Disclosed is an arrangement that enables to keep a relative positional relation between a beam for servo control and a beam for information recording/reproduction constant concerning focusing control and tracking control, even if the two beams are different from each other. An optical storage medium has a reflection surface for reflecting a first beam having a first wavelength, and reflecting a second beam having a second wavelength different from the first wavelength; and an information storage layer for recording information as an interference pattern by incidence of the first beam, or reproducing the information from a wave surface based on the interference pattern. The reflection surface is formed with plural marks or guide grooves usable in a tracking operation or a focusing operation by irradiation of the second beam. The information storage layer is partially formed, in advance, with a reference interference pattern which is reproduced when the first beam is irradiated, and which is used as a reference for correcting the relative positional relation between the first beam and the second beam.

    • Disclosed is a liquid crystal display device, which is capable of reducing a required response speed and increasing a pixel aperture ratio, as compared with a field sequential driving scheme. A unit pixel of a liquid crystal display panel is made up of a first sub-pixel adapted to allow only any two of red, green and blue lights to pass therethrough, and a second sub-pixel adapted to allow only a remaining one of the red, green and blue lights to pass therethrough, wherein one frame of image is time-divided into n pieces (wherein n is an integer of two or more), and respective image information about the two lights are applied to the first sub-pixel during every duration of the 1/n frame, while applying image information about the remaining one light to the second sub-pixel during a duration of the one frame of image. Further, the respective two lights are emitted during every duration of the 1/n frame in synchronization with applying the respective image information about the two lights, while continuously emitting the remaining one light during the duration of the one frame of image.
