Abstract: PURPOSE:To use the object device with the beam of a large area, high polarization degree and strong light source by arranging a polarization means between the light source and a light valve and transmitting the polarization beams of the same vibration surface through plural polarization elements having different composition continuously. CONSTITUTION:The polarization means 12 consists of plural polarization elements 18, 20 of a type absorbing a useless beam and having different composition. A beam having the vibration surface of the kind of the light source 10 is emitted and the polarization beams of the same vibration surface is generated by the polarization elements 18, 20 continuously. An analyzer 16 is arranged so as to transmit the polarization beam of the vibration surface perpendicular to the vibration surface of the polarization beam of the polarization elements 18, 20.
