論文是以可撓式的概念，利用聚醯亞胺(polyimide；PI)作為可撓式的基板製作有機發光二極體(Organic light emitting diode；OLED)元件。由於PI有優異的可加工溫度，能耐300℃以上的高溫，能克服氧化銦錫(Indium Tin Oxide；ITO)的高溫製程環境。本論文實驗主軸主要分為：（Ⅰ）可撓式下發光有機二極體元件(bottom emitting oled device；BOLED)。此部分針對可撓基板可以應用於下發光元件，使可撓式基板的效率能與玻璃基板相同，之後，更進一步地藉由混摻二氧化矽或二氧化鈦於聚醯亞胺中，調整基板折射率(Refractive index)提高元件的出光(light coupling)進而提升元件的效率。（Ⅱ）可撓式上發光有機二極體元件(top emitting oled device；TOLED)。以文獻探討做為參考，從多種材料中選取了上發光元件陽極與電洞注入層(Hole injection layer)，接著對上發光元件最重要的透明電極進行一系列的測試與，再將電洞傳輸層的膜厚最佳化使微共振腔效應達到最大化，進而提升元件效率。最後再將有機上發光元件應用於聚醯亞胺基板上，並達成高效率可撓式有機二極體元件的目標。

With the flexible concept, this research uses polyimide (PI) as the component in the manufacture of substrate for Organic Light Emitting Diode (OLED). As PI features excellent processing temperature and resists a high temperature of over 300℃, enabling to overcome the manufacturing environment of Indium Tin Oxide (ITO).The Laboratory has not yet developed any flexible devices in the past. The experiment is divided into two parts: (I) bottom emitting oled device (BOLED). In this part, the flexible substrate is applied in BOLED and its refractive index can be further adjusted, enhancing the lighting coupling and efficiency of components.
(II) top emitting oled device (TOLED). Based on research documents and discussions, the hole injection layer in TOLED is chosen, plus the use of transparent cathode, the most important of its kind from multiple materials. Microcavity has to reaches its maximum status to ensure the efficiency. Thus, such components can be used in PI substrate and emulate the same lighting efficiency as that of glass substrates.
