The present invention provides a light-diffusing member having no non-uniformity in stripes. The light-diffusing member according to the present invention is for diffusing at least a part of transmitted light by totally reflecting the same. The light-diffusing member comprises a light-diffusing part that has a diffusing-part base having a plurality of grooves tapered down toward the incident side, formed on the light-outgoing side in juxtaposition with one another, and light-absorbing parts formed, in the grooves in the diffusing-part base, by a radiation-curing resin composition. The radiation-curing resin composition includes colored particles. The colored particles have a mean particle diameter of 3.5 μm or more and 20 μm or less.
