PROBLEM TO BE SOLVED: To improve the light resistance or the heat resistance of a micro lens array substrate.SOLUTION: A micro lens array substrate 10 comprises: a transparent substrate 11 whose upper surface 11a has a first recess 12; a first transparent layer 13 that is formed to cover the first recess 12, has a second recess 14 where the shape of the first recess 12 is reflected on an upper surface 13a that is on the opposite side of a lower surface 13b being in contact with the upper surface 11a, and has a refractive index higher than the refractive index n0 of the transparent substrate 11; and a second transparent layer 16 that is formed to cover the second recess 14 and has a refractive index n2 different from the refractive index n1 of the first transparent layer 13. The first transparent layer 13 and the second transparent layer 16 are made of an inorganic material.SELECTED DRAWING: Figure 4
