Optical element, planar lighting unit and liquid crystal display unit |
摘要 |
An optical element is arranged between a planar lighting element and a liquid crystal panel for harvesting light that exits from the planar lighting element. The optical element has an incidence plane and a plurality of protrusions. The light that exits from the planar lighting element enters into the optical element. A plurality of the protrusions is provided on a surface facing the incidence plane. Substantially all the protrusions are each arranged in a one-to-one correspondence with an opening of a respective pixel of the liquid crystal panel. <IMAGE> |
