POLARIZATION TRANSFORMATION FILM, POLARIZATION ELEMENT, LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD FOR MANUFACTURING POLARIZATION TRANSFORMATION FILM |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a polarization transformation film having superior productivity and by which light utilization efficiency is increased and particularly, a brightness enhancement effect is high in a reflection type and a semitransmission type liquid crystal display element. <P>SOLUTION: The polarization transformation film comprises: a polarization separating layer 1 separating non-polarized incident light L into two straight line polarization in which electric field vectors are orthogonally intersected each other; and a polarization transformation layer 2 transforming the polarization state of the straight line polarization. The polarization separating layer 1 consists of a prism and a birefringence layer having birefringence. The polarization transformation layer 2 consists of a birefringence compound m slantly-oriented with respect to a film surface. <P>COPYRIGHT: (C)2004,JPO |
