<p>PURPOSE:To obtain a compact head-mount type display device with a light weight without emission of harmful electromagnetic wave giving adverse effect on a human body to protect the health of a person wearing the display device and used for another electronic device without electromagnetic interference. CONSTITUTION:Electromagnetic shield is applied electrically to an entire optical unit 2 comprising a liquid crystal display device 3, a reflecting mirror 4 and a magnification lens 5 and an ITO film 101 is formed on the surface of the display element 3 or the surface of the magnification lens 5 being an output incidence optical path of a displayed video image of the display element 3. Then the ITO film 101 connects electrically to ground in common to the electromagnetic shield of the optical unit 2 and the electromagnetic shield of a display element control circuit 8.</p> |
