A lenticular lens sheet having rows of cylindrical lenses on the incident surface side, having projections on those sections of the lens rows where light is not condensed, and having light absorption layers on the projections. The pitch of the lens rows is smaller than 0.5 mm, the angle ?1 between the lowermost section of a projection and a sheet main surface is equal to or greater than 45° and is greater than the angle ?2 formed between the vertex of the projection and the sheet main surface, and the width of the projection measured at a position 10 µm away in the sheet thickness direction from the vertex of the projection is equal to or smaller than 150 µm. Even if the pitch of the lens row is small, light shielding layers on the projections of the lenticular lens can be uniformly formed in a sufficient thickness by a simple means, and as a result, the contrast of external light is increased.
