Top emission organic light emitting diode display using auxiliary electrode to prevent voltage drop of upper electrode and method of fabricating the same
摘要：
An organic light emitting diode (OLED) display. The OLED display includes: a lower electrode formed on a layer on an insulating substrate having a thin film transistor. The lower electrode is electrically connected to the thin film transistor. An auxiliary electrode is formed on the same layer as the lower electrode, and a pixel defining layer is formed on edges of the lower electrode, thereby defining an opening which exposes a portion of the lower electrode. An organic layer is formed on the portion of the lower electrode exposed by the opening, and an upper electrode is formed on an entire surface of the insulating substrate and electrically connected to the auxiliary electrode. An edge of the auxiliary electrode may have a taper angle of at least 90°.

有机发光二极管（OLED）显示器。 OLED显示器包括：形成在具有薄膜晶体管的绝缘基板上的层上的下电极。 下电极电连接到薄膜晶体管。 辅助电极形成在与下电极相同的层上，并且像素限定层形成在下电极的边缘上，从而限定了暴露下电极的一部分的开口。 在由开口露出的下部电极的部分上形成有机层，并且在绝缘基板的整个表面上形成上电极，并与辅助电极电连接。 辅助电极的边缘可以具有至少90°的锥角。
