Reflective screen, reflective screen unit, and video display device

A reflective screen which observably displays by reflecting video light projected from a video source, the reflective screen comprising:

• a lens layer having a Fresnel lens shape in which a plurality of unit lenses are arranged;
• and
• a reflective layer which is formed on the unit lens of the lens layer, and reflects light,
• wherein the unit lens is convex towards a back surface side from a video source side in a thickness direction of the lens layer,
• wherein a flat part at which a part of a back surface side becomes a flat surface is formed in at least an edge of the lens layer, and
• wherein, in a thickness direction of the lens layer, a smallest lens height h1min of a lens height h1, which is a distance from a position that is a most video source side of the lens layer until a position that a most back surface side of the unit lens, and a height h2 which is a distance from the flat surface of the flat part until a position which is a most back surface side of the unit lens satisfy a relationship (h1min−h2)>0.
