US Patent 9209414 Display device

A display device is discussed which can include: a flexible substrate defined into a first area, a second area bent from an edge of the first area, and a third area outwardly expanded from the second area; a thin film transistor layer disposed on the substrate; an organic emission layer disposed on the thin film transistor layer; an encapsulation layer disposed on the organic emission layer; a polarization layer disposed on the encapsulation layer; and a cover window disposed on the polarization layer. The polarization layer is formed on the encapsulation layer opposite to the first and third areas of the substrate.
