顶部发光型有机电致发光显示设备及其制造方法
摘要：
一种顶部发光型有机电致发光显示设备，包括：包含像素区域的第一基板；在第一基板上的像素区域内的开关薄膜晶体管和驱动薄膜晶体管；覆盖开关薄膜晶体管和驱动薄膜晶体管和暴露驱动薄膜晶体管的漏电极的钝化层；在钝化层上并连接驱动薄膜晶体管的漏电极的连接电极；与相邻像素区域之间的边界对应和重叠连接电极的边沿部分的隔离墙；在相邻隔离墙之间、位于连接电极上的X射线屏蔽层，该X射线屏蔽层由于隔离墙的缘故在像素区域内被自动地形成图案；在X射线屏蔽层上的第一电极；覆盖隔离墙并连接第一电极的边沿部分的基台；在相邻基台之间、位于第一电极上的有机发光层；在有机发光层上的第二电极；和面对第一基板并透明的第二基板。
摘要（英）：

A top emission type organic electroluminescent display device includes a first substrate including a pixel region, a switching thin film transistor and a driving thin film transistor in the pixel region on the first substrate, a passivation layer covering the switching thin film transistor and the driving thin film transistor and exposing a drain electrode of the driving thin film transistor, a connection electrode on the passivation layer and contacting the drain electrode of the driving thin film transistor, a partition wall corresponding to a border between adjacent pixel regions and overlapping an edge portion of the connection electrode, an x-ray shield layer on the connection electrode between adjacent partition walls, the x-ray shield layer automatically patterned in the pixel region due to the partition wall, a first electrode on the x-ray shield layer, a bank covering the partition wall and contacting an edge portion of the first electrode, an organic emission layer on the first electrode between adjacent banks, a second electrode on the organic emission layer, and a second substrate facing the first substrate and being transparent.
