PURPOSE:To use a projection lens having an F value equal to that obtained when a lenticular microlens and a polarizing optical system are used independently of each other by combining the lenticular microlens and the polarizing optical system together in using them. CONSTITUTION:A projection type liquid crystal display is so designed that the direction of alignment of lenticular microlenses 6 is perpendicular to the direction of alignment of first and second outgoing beams 5, 6 of light emitted from a polarizing optical system 3. |
