PURPOSE: A both sided screen for three-dimensional and two-dimensional images is provided to use one between front or rear surface of one screen as a screen of polarized 3D images or reflective screen of the high efficiency and use the other as the screen of high definition of high contrast. CONSTITUTION: A both sided screen for three-dimensional and two-dimensional images comprises a reflection layer(3). The reflection layer is formed by evaporating or spreading aluminum in a surface of a screen material(4) and the other surface(4a) of the screen material is composed of white color materials having a particle size of 80 to 1500 meshes so that a surface(2) of a screen has a function of a 3D image screen or a highly reflection screen. The other surface of the screen material has a function of highly definition screen or wide viewing angle screen. |
