Abstract

A reflection sheet (10) has a wide observation angle and can control the direction of effectively reflected light in a specific observation angle range while maintaining the wide observation angle characteristics. The reflector (10) comprises a base layer (5) having a plurality of minute convex mirrors (61) and concave mirrors (510) provided on the surface (51) of said base layer (5), said mirrors being adjacent to each other. The sheet provides a bright reflection and is particularly useful as a construction part of an image-displaying sheet.
