Problems solved by technology

As long as this exposure method is used, it is difficult to increase the size of the screen due to the limitation of the manufacturing method
In addition, in order to obtain different viewing angle characteristics between vertical and horizontal directions, multiple exposures are required, which makes the manufacturing process more complex
[0008] Furthermore, there is a problem in Japane

Embodiment Construction

[0027] The present invention will be described below according to preferred implementations. The purpose of these preferred embodiments is not to limit the scope of the present invention, but to illustrate the present invention. All the features of the present invention described in the embodiments and combinations thereof are not necessarily essential to the present invention.

[0028] figure 2 is a view showing the basic structure of the reflective screen 2 according to the embodiment of the present invention. The reflective screen 2 includes a base material 5 having a projector-side slope 3 and a non-projector-side slope 4 , and a white resin layer 6 . The base material 5 is made of a light-absorbing material. Set the projector side slope 3 at an angle so that light from projector 1 enters the projector side slope 3, and set the non-projector side slope 4 at an angle so that light from projector 1 does not enter the non-projector side slope 4, and the projector-side slop...

Abstract

A reflex-type screen for reflecting a light projected obliquely from a projector to a front of the reflex-type screen, including a base material made of material which absorbs light, a white resin layer which is formed on a projector side inclined plane on the base material and reflects light and a transparent diffusing layer which includes transparent binder resin and diffusing agent, and is formed to cover the white resin layer, and the base material includes the projector side inclined plane that is provided at an angle so that light from the projection enters the projector side inclined plane and a non-projector side inclined plane that is provided at an angle so that the light from the projection does not enter the non-projector side inclined plane, and the projector side inclined plane and the non-projector side inclined plane are located alternatively, so that the base material is formed to be saw-toothed shape. The white resin layer reflects the light from the projector to the front of the reflex-type screen, and the non-projector side inclined plane absorbs almost of incident light, and the transparent diffusing layer diffuses light which is reflected by the white resin layer.

Description

[0001] This application claims the benefit of Japanese Patent Application No. 2004-139017, filed May 7, 2004, and Japanese Patent Application No. 2004-170496, filed June 8, 2004, the entire contents of which are incorporated herein Reference. technical field [0002] The invention relates to a reflective screen. More particularly, the present invention relates to a reflective screen for reflecting obliquely projected light from a projector to the front of the reflective screen. Background technique [0003] Conventionally, as shown in FIG. 1 , there has been a need to display an image to a viewer located in front of the screen by obliquely projecting imaging light onto the reflective screen from a short distance from the reflective screen. When a commonly used white matte screen is used for the above purpose, most of the imaged light projected from the short-focus projector 21 is reflected outside the viewer's position, thereby failing to provide uniformity to the viewer in...
