摘要

The projection display device according to the present invention comprises a light source; A linear light illumination system for converting light emitted from the light source into a thin line light; A linear optical modulator for displaying an image by converting a direction and an amount of light emitted from the linear light illuminator; A scanner scanning the linear image emitted from the linear optical modulator in a specific direction; A projection lens that enlarges and projects an image scanned by the scanner; And a screen for imaging an image output through the projection lens to enjoy a screen.;The linear light illumination system includes an optical shape conversion lens for converting light from a light source into a linear light shape; A rod lens for uniformly distributing the amount of light emitted from the optical shape conversion lens and forming the shape in a thin plate shape to maintain a linear light shape in the shape of the plate shape; And an illumination lens for focusing and illuminating the linear light emitted from the rod lens in the size and shape of the linear optical modulator.;Linear light system, optical conversion lens, rod lens
