Abstract: A display device includes a screen having opposite ends and a curved surface between the opposite ends, the curved surface being protrudingly curved toward a side opposite to a display observation side. First and second display elements are respectively provided at the opposite ends of the screen, and display two different sub-images constituting one image. The display elements are arranged in such a manner that sub-image lights of these sub-images are transmitted toward an inner side from corresponding areas on an outer side of the curved surface in end sections of the screen to be applied to the inner side of the curved surface of the screen and sub-image lights are reflected on the inner surface of the curved surface of the screen to enter right and left eyes of an observer, respectively.

Abstract: A display device includes an image display unit having one surface and the other surface on which first and second images are respectively displayed. A first optical system leads a first image light displayed on the one surface of the image display unit. A second optical system leads a second image light displayed on the other surface of the image display unit. An image combining element combines the first and second image lights lead by the first optical system and the second optical system to form one image.

Abstract: An illumination panel comprises a light source, a photoconductor for guiding light from the light source, and an optical film for emitting light emitted from the photoconductor ahead of an observer. The photoconductor comprises a stepwise face having an incident end face onto which the light from the light source is projected, step faces, and step differentiating faces for emitting the light guided from the light source and connecting the step faces, and reflective films formed on the step faces. The optical film is arranged at the front side of the photoconductor, and has projected incident portions which are opposite to the step differentiating faces in a light emitting direction. The optical film emits the light emitted from the step differentiating faces ahead, and causes the light that is projected from the front to be reflected ahead on reflective faces on the step faces. In the incident portions, one of side faces opposite to the step differentiating faces of the photoconductor makes an incident face for receiving the light emitted from the step differentiating faces, and the other makes a refractive face for reflecting/refracting the light taken in the incident face toward its front face. A liquid crystal display element is arranged at the front of this illumination panel so that they constitute a liquid crystal display device.

Abstract: A surface light source device includes a light source, a light guide plate for guiding light from the light source to one surface, and a light-condensing member for outputting exit light from the light guide plate in a predetermined direction. The one surface of the light guide plate is a stepped surface whose thickness decreases step by step at a predetermined pitch from one end, at which the light source is arranged, to the other. The light-condensing member is located to face the light guide plate and includes a plurality of prisms for refracting exit light from the light guide plate toward the direction of a normal to the light guide plate, and a plurality of lenses for condensing and outputting light in a direction within a predetermined range of angles.
