Claim:
A multi-layered micro lens sheet for a three-dimensional look, comprising: a lens array layer in which first convex lenses and second convex lenses with different shapes are alternately arranged in longitudinal and transverse directions; a focal distance controlling transparent resin layer formed under the lens array layer; and a three-dimensional layer formed under the focal distance controlling transparent resin layer so that a three-dimensional image can be observed from the three-dimensional layer, wherein the multi-layered micro lens sheet further comprises at least one of: a first resin coating layer formed over the lens array layer; and a second resin coating layer formed between the focal distance controlling transparent resin layer and the three-dimensional layer, wherein the lens array layer and the focal distance layer are formed of A-PET (A-polyethylene terephthalate), and the first and second resin coating layers are formed of G-PET (G-polyethylene terephthalate).
