ORGANIC ELECTROLUMINESCENT DEVICE

摘要

According to an embodiment, an organic electroluminescent device comprises: a substrate; a first electrode formed on the substrate; banks arranged along the edge of the first electrode and forming a protrusion on the side; an organic light emitting pattern arranged between the banks; and a second electrode arranged on the bank and the organic light emitting pattern. The protrusion is formed on the side of the bank so that light emitting areas between the banks are widened. Accordingly, the present invention has high resolution and can improve dripping accuracy of ink.
