Provided are organic-inorganic hybrid polyamic ester, method of fabricating the same, and method of fabricating a film thereof. The polyamic ester is formed by chemically reacting an inorganic precursor containing inorganic and/or metal element with a polyamic acid having two carboxyl acid of good reactivity per a polymer repeating unit. The inorganic alkoxide is hydrolyzed to be the corresponding inorganic hydroxide. The hydroxyl group is reacted with the carboxylic acid of the polyamic acid and with the hydroxyl group of the other inorganic hydroxide. Therefore, the polyamic ester can steadily include more inorganic materials. The content amount of the inorganic material is relatively high, so that the polyamic ester may have superior refractive index, chemical and heat resistances.

Provided is a transparent organic light emitting diode (OLED) lighting device in which opaque metal reflectors are formed to adjust light emitting directions. The transparent OLED lighting device includes a transparent substrate, a transparent anode formed on a predetermined region of the transparent substrate, a reflective anode formed adjacent to the transparent anode on another region of the transparent substrate, an organic layer formed on the transparent and reflective anodes, and a transparent cathode and an encapsulation substrate sequentially stacked on the organic layer. Directions of light emitted from the organic layer vary depending on the current applied to the transparent and reflective anodes.
