OPTICAL ELEMENT, DISPLAY DEVICE, AND OPTICAL DEVICE |
摘要 |
<p>A retardation film includes a plurality of unit areas in a direction parallel to a light-incident plane of the optical element, and the unit areas includes a plurality of unit areas 2 whose retardation with respect to light of a certain wavelength is different by 10nm or more from retardation of adjacent unit areas with respect to light of the certain wavelength. The retardation film utilizes a difference in wavelength dependence between retardation r(n, ») of each of the unit areas and synthetic retardation R(») of a whole area including all of the unit areas. This realizes an optical element capable of easily controlling wavelength dispersion of retardation, without being constrained by a material.</p> |
