Abstract
An organic light emitting device having an overlapped area located at an edge of a non-display area. The organic light emitting device includes: a first electrode, a pixel definition layer, an isolation layer and a second electrode. The first electrode is arranged on a planarization layer of the overlapped area. The pixel definition layer is arranged on the first electrode, and further includes a number of pixel definition blocks. The isolation layer is arranged on the pixel definition layer, and further includes a number of supporting blocks arranged in a manner same to that of the number of pixel definition blocks of the pixel definition layer. The second electrode covers the first electrode, the pixel definition blocks, and the supporting blocks in the overlapped area. the second electrode overlaps the first electrode.
