Abstract: A projection-type 3-D image display device includes a single display element, a polarization conversion switch, a first image shifter, a second image shifter, a projection lens unit, a mirrored light tunnel, and a screen unit. The screen unit includes an image separation unit. The single display element emits light polarized in a first polarization direction according to an input image. The polarization conversion switch time-sequentially converts the first polarization direction of the light emitted by the display element into a second polarization direction. The first image shifter transmits the light having the first polarization direction to form a first image and refracts the light having the second polarization direction to form a second image. The second image shifter faces the first image shifter and is arranged apart from the first image shifter by a predetermined interval. The projection lens unit enlarges and projects the first and second images. The mirror light tunnel allows the first and second images to be focused to different view points. The image separation unit delivers the first and second images to the left and right eyes, respectively.
