  • Patent number: 7330311
    Abstract: There is provided a transmission type screen having a directional light scattering lens and a fresnel lens, wherein the fresnel lens has contact portions that contact with the directional light scattering lens and non-contact portions which are provided between the contact portions, whose height is lower than that of the contact portions and which do not contact with the directional light scattering lens. The invention realizes the very practical transmission type screen that allows viewers to appreciate good images in which blur and Moire are inconspicuous by preventing the blur from occurring on the screen and by reducing the intensity of Moire which is caused by the periodic structure of the fresnel and lenticular lenses.
