摘要： A projection apparatus includes at least one light source, a field lens, a light valve, and a projection lens. The light source provides an illumination beam. The field lens is disposed in a transmission path of the illumination beam including an effective beam passing through the field lens and a ghost beam reflected by the field lens. The effective beam forms a light spot on the light valve capable of converting the effective beam into an image beam. The projection lens is disposed in a transmission path of the image beam and a ghost beam path of the ghost beam. A center of the light spot does not overlap a center of the light valve. An offset direction from the light valve to an optical axis of the projection lens is the same as a direction from the center of the light valve to the center of the light spot.

The polarization beam splitter is disposed on the transmission path of the illumination beam between the illumination system and the first lens group. The polarization beam splitter permits the illumination beam to pass through and travel to the reflective light valve. The reflective light valve modulates the illumination beam to an image beam traveling to the polarization beam splitter. The polarization beam splitter reflects the image beam to the second lens group.
