摘要：
An OLED (Organic Light Emitting Diode) device can include a red emission layer, a green emission layer, and a blue emission layer which are non-patterned and stacked as common layers configured such that a thickness of each of a hole transporting layer, the red emission layer, the green emission layer, and the blue emission layer is respectively less than those corresponding layers in a conventional OLED device having a red emission layer, a green emission layer, and a blue emission layer which are patterned.
