An ink composition for inkjet printing organic light-emitting diodes and a method of manufacturing the same are disclosed. The ink composition includes 0.01-40% of bipolar light emission component, 10-99.9% of solvent, 0.01-5% of surface tension modifier, and 0.01-5% of viscosity modifier by weight. The method of manufacturing the ink composition includes steps of: dispersing the bipolar light emission component in the solvent firstly, and then adding the viscosity modifier and the surface tension modifier under stirring, so as to obtain the ink composition. By using the ink composition, specific hole and electron transport layers provided in the organic light-emitting diode manufactured by inkjet printing may be omitted, thereby simplifying the structure of the organic light-emitting diode. Moreover, the ink composition has suitable viscosity, surface tension, and volatility.
