Abstract
An object of the present invention is to provide a retardation layer laminate capable of improving the adhesion between liquid crystal retardation layers. The retardation layer laminate of the present invention comprises, in order, a first liquid crystal retardation layer, a first bonding layer, and a second liquid crystal retardation layer. Among the aforementioned first liquid crystal retardation layer and second liquid crystal retardation layer, the one having a relatively smaller peel force with respect to the first bonding layer has an atomic concentration of Si atoms of
