摘要：An improved polarizer employing thin films is provided having higher opticalproperties and capable of fabricating in the mass production and reducing in the overallsize or thickness. Particularly, a layer of optical element for polarizing separation of lightextends over an undulated surface of a substrate having a cross section of eithertrapezoid-waveform or triangle-waveform oriented in a particular direction. The

substrate having a trapezoid-waveform surface incorporates layers of optical element forreflection or absorption of light which are provided on the upper- and lower-baseregions, excluding the sloping regions, of the trapezoid-waveform surface. On the otherhand, the substrate having a triangle-waveform surface incorporates layers of opticalelement for absorption of light which are provided on the upper and lower peak regionsof the triangle-waveform surface.
