ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE

摘要

PURPOSE: An organic light emitting diode display device is provided to maximize a light extraction effect by forming a capping layer including silver on the upper part of a second electrode. CONSTITUTION: A first electrode(147) is formed on the upper part of a substrate. A hole transport layer includes a first material. A light emitting layer includes a second material. An electron transport layer includes a third material. A capping layer(250) is formed on the upper part of a second electrode(158).
