Patent ID: 8310153

Claim:
An organic light emitting diode (OLED) display device, comprising: a base substrate including a first device region and a first encapsulation region, wherein the first encapsulation region is located on opposing sides of the first device region; an organic light emitting diode (OLED) disposed on the first device region; an inner filler formed over the OLED and the first device region; a light transmission layer continuously formed on the inner filler; an encapsulation substrate including a second device region and a second encapsulation region corresponding to the first device region and first encapsulation region, respectively, wherein the second device region is formed over the light transmission layer; and an encapsulation agent disposed on the first and second encapsulation regions, and configured to encapsulate the base substrate with the encapsulation substrate, wherein the light transmission layer has a refractive index ranging from about 1.75 to about 1.85.
