Abstract: An object of the present invention is to provide a display device that can be manufactured more easily than the conventional one. To accomplish this object, an image control panel part (7) which is continuously provided with combination base units including optical transparency base units and optical no-transparency base units, and a lens film part (6) which is continuously provided with repeating units of lenses (8) are laminated in a direction of light transmission, and either one width of the optical transparency base unit or a pitch of the repeating unit of the lens is set so as to be the integral multiplication of the other width. Since the moiré´ fringes can be prevented by setting either one width of the optical transparency base unit or the pitch of the repeating unit of the lens 8 so as to be the integral multiplication of the other width, it is not always necessary for the display device of the present invention to change a pitch of the mold for manufacturing the lens film part 6 randomly.

Abstract: The invention relates to high-strength, abrasion-resistant optical fiber cable having a supplemental layer consisting essentially of a liquid crystal polymer (LCP) to enhance the cable's tensile strength and hermetically seal it, and an outermost encasing layer to protect the LCP supplemental layer from damage that could otherwise diminish the tensile strength or destroy the moisture barrier properties of the cable gained by adding the supplemental liquid crystal polymer layer. The encasing layer is preferably a thin layer of a smooth, non-crystalline thermoplastic that can be easily removed with chemicals that do not affect the properties of the supplemental layer so that the supplemental layer can be made accessible for promoting the formation of hermetically sealed interfaces between the cable and other structures. Cross-head extrusion methods for coating optical fibers with LCP and encasing layers are described along with laser and ultrasonic bonding techniques for fabricating hermetic packages.
