INTEGRATOR COMPRISING POLARIZER AND LIQUID CRYSTAL DISPLAY PROJECTOR USING THE SAME, IN WHICH AN INTEGRATOR IS USED

摘要

PURPOSE: An integrator comprising a polarizer is provided which has a long life time and is formed with low cost. CONSTITUTION: According to an integrator comprising a polarizer, one integrator(10) selected among a rod integrator or a tunnel integrator comprises a light incident part where a light is incident from a light source and a light output part radiating the light. A reflective type polarizer(30) is comprised in the light output part of the integrator, and has a conductor where a stripe shape is patterned repetitively on one surface of a transparent substrate. And the second polarizer(40) is comprised in a back of the reflective type polarizer and polarizes the light polarized through the reflective type polarizer.
