摘要： An object of the present invention is to effectively alleviate surface plasmon absorption at the cathode of an organic EL lighting and improve the light extraction efficiency. An organic EL (electroluminescent) device of the present invention includes a translucent substrate, a transparent electrode, a luminescent layer, and a cathode placed over one surface of the translucent substrate, and a light extraction film having unevenness placed on the other surface. The surface of the cathode facing the luminescent layer has a plurality of recesses or protrusions. The Fourier transform image of the surface of the cathode facing the luminescent layer has a surface plasmon absorption suppression area including a spatial frequency v obtained from Eq. (I) and a light scattering area not including spatial frequencies equal to or greater than the spatial frequency ν.

摘要： An integrated three-dimensional display (10) includes a recording surface (14) which includes a calculated element region (16) in which phase components of light from light converging points (Sn) of a holographic reconstructed image (40) are calculated, and a phase angle recorded area (18) for recording a phase angle calculated based on the phase components. The phase angle recorded area (18) includes a plurality of monochromatic regions (22) having a uneven structure surface. The phase angle is recorded in an overlap area (19) in which the calculated element region (16) and the phase angle recorded area (18) overlap each other. Light converges on the light converging points (Sn) at specific distances (Zn) from the recording surface (14), the specific distances being determined for the respective light converging points (Sn) even when light reflected from the plurality of monochromatic regions (22) converges.
