摘要： An optical film may include a polarizer configured to linearly polarize a first light to provide a linearly polarized light component. The optical film may further include a first semi-transmissive film overlapping the polarizer, configured to transmit the linearly polarized light component, and configured to reflect a first circularly polarized component of a second light. The first circularly polarized component of the second light may have a first wavelength. The optical film may further include a second semi-transmissive film overlapping the first semi-transmissive film, configured to transmit the linearly polarized light component, and configured to reflect a second circularly polarized component of the second light. The second circularly polarized component of the second light may have a second wavelength that is unequal to the first wavelength.
