Abstract
A projector of a reflection type has a Fresnel lens disposed under a stage surface on which a transparency is set. A light source is disposed under the Fresnel lens, and illuminates the stage surface through the Fresnel lens. An illuminating mirror is disposed in a position higher than the stage surface, reflects light passed through the transparency after emanation from the light source, and illuminates the transparency downwards. A projection lens projects an image of the transparency via the Fresnel lens to a screen. A liquid crystal display (LCD) panel is disposed so that the stage surface lies thereon, and displays an image to be projected to the screen. The LCD panel is transparent when the transparency is set on the stage surface, and enables projection of the image.
