PURPOSE:To provide the reflection base material which uniformly diffuses light and is used for a liquid crystal display device and illuminating device, etc. CONSTITUTION:This reflection base material is constituted of a base material (A); a coating layer (B) which contains spherical particles (P) having an average particle size in a 0.2 to 10mum range and the standard deviation value of the particle size in a 1.0 to 1.3 range and in which the ruggedness of the coating layer occurring in the above-mentioned spherical particles (P) has the surface center line average height in a 0.03 to 1mum range, and the surface average inter-peak spacings in a 0.2 to 30mum range and the coefft. of fluctuation in the surface average inter-peak spacings within 20% on the smooth surface of the base material (A); and a metallic layer (C) having 0.01 to 1mum thickness on the surface of the coating layer (B). |
