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.
