Embodiment Construction

[0027] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0028] Hereinafter, an organic electroluminescence device and a manufacturing method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

[0029] The dimensions of thickness are exaggerated in the drawings to clearly show several layers and regions. The thickness ratios of the respective layers shown in the drawings are not equal to the actual thickness ratios. Meanwhile, when a part such as a layer, a film, a region, and a plate is formed or provided "on" another part, it should be understood that the part may be directly formed on the other part by direct contact, or may be provided with another part in between. part.
