Abstract
A laminate can include a first panel and including a first transparent substrate having a first refractive index. The laminate can further include a second panel and a third panel, each coupled to the first panel. The second panel includes a second transparent substrate having a second refractive index, and the third panel includes a third transparent substrate having a third refractive index. The laminate can further include a fill material disposed within a gap between the second and third panels and having a fill material refractive index. The fill material refractive index is within 0.09 of the second refractive index, the third refractive index, or a value between the second and third refractive indices. Coupling may be direct or may be achieved with an adhesive film. The fill material can help to reduce the likelihood of seeing seams between the second and third panels.
