Title:
LAMINATED FILM FOR BONDING AND LIGHT-TRANSMITTING LAMINATE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/222401
Kind Code:
A1
Abstract:
An embodiment relates to a laminated film for bonding, a light-transmitting laminate, and the like, the laminated film comprising: a first layer including a first surface, and a second surface facing the first surface; and a second layer located inside the first layer and including a wedge portion having a triangular or trapezoidal cross section in at least part or all of the second layer, wherein the refractive index of the second layer is greater than that of the first layer. The laminated film for bonding has an overall uniform thickness, so that the entire laminated film for bonding has a substantially non-wedge shape, but has a function of preventing double images in an intended part, thereby making it possible to provide a bonding film for a head-up device that is superior to a wedge-type film in storage, movement, and workability.
