A reflective screen includes a light reflecting layer, and a light diffusing layer provided on the light reflecting layer. The light diffusing layer has the diffusion property that in one (A axis) of two perpendicular axial directions on a light diffusion plane, a luminance distribution curve versus incidence angle is asymmetric with respect to the zero-incidence-angle axis, and the side on which the incidence angle (half-luminance incidence angle) with half of a peak luminance on the A axis in the normal direction to the screen plane is small faces in a direction in which external light has the highest strength.

An optical element laminate is provided which, while an increase in thickness of a liquid crystal display device is suppressed, improves insufficient rigidity of an optical element and, in addition, which does not degrade display characteristics of the liquid crystal display device. The optical element laminate includes a plate-shaped support member having a first primary surface and a second primary surface and an optical element which is laminated on at least one of the first primary surface and the second primary surface of the support member and, in addition, which has a film shape or a sheet shape. The periphery of the laminated optical element is at least bonded to facing two sides of the support member, the optical element and the support member are placed in close contact with each other, and a thickness t of the support member, a length L of the support member, and a tensile force F of the optical element satisfy the relational expression of 0≦F≦1.65×104×t/L in an environment at a temperature of 70° C.

An optical element covering member is provided which can suppress degradation in display performance caused by warping and undulation. The optical element covering member includes at least one optical element, a support medium supporting the optical element; and a covering member covering the optical element and the support medium.

An optical sheet laminate body includes: a first optical sheet having a top surface and a bottom surface, of which at least the top surface has asperities including projections and depressions; and a second optical sheet having a top surface and a bottom surface. Summits of the projections on the top surface of the first optical sheet are directly bonded, in a whole region facing the bottom surface of the second optical sheet, to the bottom surface of the second optical sheet without any intermediate material in between.
