PROBLEM TO BE SOLVED: To provide a microlens array sheet having uniform optical performance, further having a preferred diffusion angle, controllable viewing angle characteristics and improved uniformity, resulting from improvements in non-uniformities of height and surface roughness of a base, which occur during a manufacturing process of the microlens array sheet, as well as a manufacturing method thereof. SOLUTION: The microlens array sheet is characterized by comprising: a transparent substrate to be arrayed with microlenses; bases formed at the same positions as microlenses to be formed later on the transparent substrate to a height determined by a user; microlenses formed on the upper portions of the bases and a gap-filling film applied on the upper portion of the resulting structure, in which the bases have the same height through a planarization process on the upper surfaces of the bases.
