Document Type and Number:
WIPO Patent Application WO/2018/084052
Kind Code:
A1
Abstract:
Provided is an optical panel 100 which does not require the presence of fine particles for the achievement of an anti-reflection function. This optical panel 100 is provided with a light-transmitting substrate 10 and an exterior layer 20 that is positioned on the substrate 10. The exterior layer 20 comprises: a first region R1 that has a relatively low reflectance with respect to incident light from the exterior layer 20 side of the optical panel 100; and a second region R2 that has a relatively high reflectance with respect to the incident light. The exterior layer 20 contains a first resin-based material and a second resin-based material; and a surface R1A of the first region R1 is provided with a group 21 of projections that are formed from the first resin-based material and protrude in the thickness direction of the exterior layer so as to scatter the outside light.
