ABSTRACT:
A dioptric element array substrate10includes: a first dioptric element array2having a plurality of first dioptric elements2aarranged two-dimensionally; a second dioptric element array4having a plurality of second dioptric elements 4a having a first refractive index arranged two-dimensionally in one-to-one correspondence with the first dioptric elements; and a third dioptric element array5having a second refractive index different from the first refractive index. Principal rays of beams incident on the first dioptric element array at different angles and converged with the first dioptric element array are collimated with the second and third dioptric element arrays.
