PROJECTION IMAGE DISPLAY DEVICE

摘要

A projection image display device 1 includes a housing 100, a projection lens 110, a front convex portion 50A and a rear convex portion 50B. The housing 100 accommodates an illumination optical system and a modulation optical system in an interior thereof. The projection lens 110 is configured to project an image modulated by the modulation optical system in a scaled-up size, and is disposed on a first lateral face 100b of the housing 100. The front convex portion 50A and the rear convex portion 50B are disposed on an intersection line between a plane containing an optical axis of the projection lens 110 and a top face 110a of the housing 100.

主权项

1. A projection image display device, comprising:
a housing including an interior and a plurality faces, each face including an exterior surface of the housing; an illumination optical system disposed in the interior of the housing; a modulation optical system disposed in the interior of the housing; a projection lens including an optical axis, the projection lens configured to project an image in a projection direction in a scaled-up size, the projection lens disposed on a first lateral face of the housing, the modulation optical system configured to modulate the image; a plane including the optical axis of the projection lens; an intersection line, the intersection line disposed at the intersection of the plane and a face of the housing; and at least one marking disposed on an exterior surface of the housing on the intersection line; wherein the at least one marking indicates the projection direction.
