Document Type and Number:
WIPO Patent Application WO/2018/154893
Kind Code:
A1
Abstract:
An optical device (1) comprises: a first translucent base material (10); a second translucent base material (20) arranged facing the first base material (10); first and second translucent electrode layers (40, 50) arranged facing each other between the first base material (10) and the second base material (20); and a light distribution layer (30) arranged between the first electrode layer (40) and the second electrode layer (50) for distributing incident light. The light distribution layer (30) includes an uneven structure layer (31) having a plurality of projections (33) each having a side face (35) capable of reflecting light and a variable-refractive-index layer (32) filling the spaces between the plurality of projections (33) for varying the refractive index according to a voltage applied between the first electrode layer (40) and the second electrode layer (50). The light distribution layer (30) is divided into a plurality of regions having different light distribution directions in plan view with each region having the side face (35) facing a different direction.
