ORGANIC LIGHT EMITTING DISPLAY APPARATUS

摘要

An organic light emitting display apparatus is provided to enhance optical efficiency by reducing angle dependency of an emitted visible ray. An organic light emitting display apparatus includes a substrate(10), a first electrode(111), a middle layer(120), a second electrode(114), and a micro-lens layer(150). The first electrode is formed on the substrate. The middle layer is formed on the first electrode and includes an organic light emitting layer. The second layer is formed on the middle layer and made of a metal. The micro-lens layer is formed on the second electrode. An interface between the second electrode and the middle layer has unevenness by patterning a surface of the middle layer facing the second electrode to have a periodic lattice structure.
