One or more aspects of the present invention relate to an optical adhesive film and a flat panel display device having the same.

Various display devices have recently been developed to replace cathode ray tubes. Examples of such display devices include liquid crystal displays (LCDs), field effect emission displays (FEDs), plasma display panels (PDPs), and electroluminescent (EL) displays.

Among these display devices, the PDP is extremely high in attention due to its simple structure and its process being regarded as being most suitable for providing a large screen. However, the PDP has low luminous efficiency and brightness, and consumes a large amount of power.

The EL display can be roughly classified into an inorganic EL device and an organic EL device in accordance with the material of the emission layer. EL display is a spontaneous device with fast response time and high Luminous efficiency, high brightness, and wide viewing angle. In particular, an organic light emitting diode (OLED) display device, which is an EL device using an organic material, requires a low direct current (DC) driving voltage, can be fabricated into a thin film display device, and can emit light having uniform characteristics. The EL device described above is easy to manufacture with respect to the pattern forming system, has high luminous efficiency, and can emit various colors of the visible light region. Therefore, research has been actively conducted in the field of OLED display devices.

In such an organic EL device, a bottom emission method or a top emission method can be established in accordance with the light emission direction. The organic EL devices can also be classified into a passive organic light emitting diode (PMOLED) device and an active PMOLED (AMOLED) device according to a driving method.
