OPTICAL DEVICE |
| 摘要 |
An optical device includes a first surface facing alight source, and including a recess portion formed in a central portion of the first surface through which an optical axis of light passes and a concave-convex pattern disposed around the recess portion, and a second surface which is disposed to oppose the first surface and at which the light incident through the recess portion is refracted and emitted externally. The recess portion may be recessed in a direction in which the light is emitted. The concave-convex pattern includes a plurality of convex portions and a plurality of concave portions alternatively and repetitively arranged in a direction outwardly from the recess portion toward an edge at which the first surface is connected to the second surface. |
