OPENED SINGLE-WALLED NANOCARBON, WATER ABSORBING AGENT CONTAINING THE NANOCARBON, AND ORGANIC LIGHT EMITTING DISPLAY DEVICE INCLUDING THE AGENT

摘要

The present invention relates to an opened single-wall nanocarbon in which an opened surface of single-walled nanocarbon is modified with a hydroxyl group (-OH) and a carboxylic group (-COOH), a moisture absorbent in which the opened single-wall nanocarbon is dispersed by a binder; and an organic light emitting display device of which an encapsulation part or a filling part is composed of the opened single-wall nanocarbon. According to the present invention, the opened single-wall nanocarbon has satisfactory adsorptive capacity for water, and can be utilized to prevent moisture from flowing into the light emitting element by composing the encapsulation part or the filling part on the outer side of a light emitting element constituting the organic light emitting display device.
