摘要： The present invention provides an optical element having a new structure that can he applied to a directional diffusion film suitably with a simpler process than before. An optical element includes a plurality of through holes in a transparent film matrix. The plurality of through holes are placed in a state where axial directions thereof are approximately in parallel with one another, and the axial directions of the through holes are inclined or approximately parallel to a thickness direction of the transparent film matrix.
