PROBLEM TO BE SOLVED: To provide a reflective screen which is reduced in reflection, is high in contrast, is high in luminance, and is satisfactory in plane uniformity. SOLUTION: The reflective screen 10 has light transmission sections 12 which are formed by lining up approximately trapezoidal shapes broader in the width on an observation surface side than the width on a rear surface side at the section orthogonal to a screen surface and can transmit light, and light absorption sections 13 which are formed alternately with the light transmission sections 12 along the screen surface at the sections thereof and absorb the light. The reflective screen 10 in which a visible angleαis regulated and the visible angleαsatisfies 40°≤θ≤70°is provided. COPYRIGHT: (C)2009,JPO&INPIT
