DISPLAY DEVICE

摘要

PURPOSE:To enable the disposition of the display device in more proximity than the focal length of the eyes by providing a liquid crystal shutter which selectively releases and shields the regions of the respective pixel images on a hologram carrier. CONSTITUTION:The liquid crystal shutter 2 releases and shields each of the parts corresponding to the respective circular graphics of the hologram. The circular graphics P are displayed as pixels in the positions where the liquid crystal 2 is opened. The displayed image is a virtual image formed by interference fringes and the circular graphics existing behind the actual position of the carrier 1 are displayed. The visual recognition of a dot matrix is possible even if the display device is disposed in more proximity than the focal length of the eyes. The liquid crystal shutter 2 is controlled to be opened and closed by a control section C disposed outside. The control section C controls the shutter to open and close by known means in correspondence to an image signal IMG. The holography image is formed on the carrier 1 by making light CL of a prescribed wavelength band on the carrier or converting white light WL by a filter to light of the prescribed wavelength band and making the light incident thereon.
