摘要： The present invention relates to a manufacturing method of a display apparatus having a display portion that is made of dot-like reflection portions. The method comprising steps of: heating at least one of a blade portion of a machining tool and a light guide plate, descending the machining tool along a specific formation direction of the blade portion all through this descending step to press the blade portion into a back surface of the light guide plate, ascending the machining tool along a specific formation direction of the blade portion all through this ascending step to pull out the blade portion from the light guide plate, moving the machining tool horizontally, and arranging at least one light source along at least one edge face of the light guide plate. The steps of descending, ascending, and horizontally moving the machining tool are performed repeatedly to form the dot-like reflection portions.

摘要： An image fiber includes an image fiber body having a twisted portion which is formed by heating, softening, and twisting a portion of the image fiber body. The rate of twist in the twisted portion is made to be constant. Moreover, the rate of twist may preferably be set in a range from 1°/mm to 4000°/mm. In addition, the rate of twist at the beginning portion of the twisted portion and the rate of twist at the end portion of the twisted portion may preferably be set in a range from 3°/mm to 400°/mm. The twisted portion may be provided with a protective element.
