  • Projection type display device with a phase modulating unit
    Patent number: 8132917
    Abstract: A projection type display device includes: a light emitting unit that includes at least one light source for emitting a coherent light. An image light generating unit modulates the light emitted by the light emitting unit to generate an image light. A projecting unit projects the image light. A phase modulating unit is arranged either between the light emitting unit and the image light generating unit or between the image light generating unit and the projecting unit and has an area where at least one of a retardation value and an azimuth direction of a slow axis is distributed respectively in different directions or values in a plane orthogonal to an optical axis.
