Abstract
An optical laminate structure including first and second layers each having a bonding face, at least one step on at least one of the bonding faces, a retarder layer between the first and second layers, and first and second adhesive layers. The first layer may cause outgassing. The retarder layer has first and second bonding faces facing the first and second layers, respectively. The first adhesive layer bonds together the bonding face of the first layer and the first bonding face of the retarder layer and has such hardness that suppresses the outgassing at an interface between the first layer and the first adhesive layer. The second adhesive layer bonds together the bonding face of the second layer and the second bonding face of the retarder layer, is more flexible than the first adhesive layer, and has such hardness as to get distorted by the step and thereby absorb height of the step.
