Abstract: An optical stack for a display device includes multiple layers that are incorporated into a display device that further includes a display panel. The optical stack includes a resin layer, an alignment film, an optical compensation layer, a polarizer, and a hard coat layer that are stacked in this order from a panel side. The optical stack is formed by preparing and coating a solution for each layer, and then curing and otherwise treating each layer as warranted for a particular layer, in turn to form the optical stack.
