Title:
OPTICAL BODY, METHOD FOR MANUFACTURING SAME, WINDOW MEMBER, SLIDING WINDOW, AND SUNLIGHT BLOCKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/096595
Kind Code:
A1
Abstract:
Disclosed is an optical body capable of minimizing glare and reflection and blocking sunlight including the visible light.
The optical body is provided with a semitransparent layer formed on a projection/recess surface and a second optical layer formed over the projection/recess surface on which the semitransparent layer is formed so as to cover the projection/recess surface. The semitransparent layer directively reflects part of the light incident on the incidence surface at an incidence angle (θ, φ) in a direction other than the direction of the angle of regular reflection (-θ, φ+180°) (where θ is an angle formed by a perpendicular (l1) perpendicular to the incidence surface and the incident light incident on the incidence surface or the reflected light allowed to exit from the incidence surface, φ is the angle formed by a specific line (l2) in the incidence surface and the component of the incident light or the reflected light projected on the incidence surface, the specific line (l2) in the incidence surface is the axis such that the intensity of reflection in the φ direction becomes maximum when the incident angle (θ, φ) is fixed and when the semitransparent layer is rotated around the perpendicular (l1) perpendicular to the incidence surface).
