Title:
OPTICAL SUBSTRATE AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/099875
Kind Code:
A1
Abstract:
Provided is an optical substrate capable of reducing color shifts due to refraction of light. An optical substrate (12) is provided with a microstructure layer including a plurality of dots (31) configured from projections or depressions, the microstructure layer extending in the out-of-plane direction from the principal plane of the substrate, the microstructure layer has a plurality of dot rows in which a plurality of dots are arranged at a pitch (Py) in a first direction in the principal plane of the substrate, and has a plurality of dot rows in which a plurality of dots are arranged at a pitch (Px) in a second direction orthogonal to the first direction in the principal plane of the substrate, and the pitch (Py) and the pitch (Px) are both indefinite intervals and are each nano-order.
