Abstract
Pre-aligned optical layers are stacked and arranged such that an adhesive layer, which is stacked onto the optical layers, contacts at least the uppermost layer and lowermost layer. The resulting subassemblies can be assembled into an optical display without individual handling of the layers, which reduces installation time and manufacturing costs.
