CARBON NANO-TUBE(CNT) LIGHT EMITTING DEVICE AND A MANUFACTURING METHOD THEREOF

摘要

A CNT(Carbon Nano-Tube) light emitting device and a manufacturing method thereof are provided to simplify a process and to reduce a cost by implementing p-n junction by coating an n-doping polymer and a p-doping polymer on both ends of a CNT thin film. A CNT light emitting device includes a CNT thin film(40), an n-doping polymer(43), a p-doping polymer(44), and a light emitting unit(42). The CNT thin film is formed by using a CNT dispersion solution. The n-doping polymer is formed on one end of the CNT thin film. The p-doping polymer is formed on the other end of the CNT thin film. The light emitting unit is formed between the n-doping polymer and the p-doping polymer. A CNT is a semiconducting CNT. A p-n junction portion is formed on an interface between the n-doping polymer and the p-doping polymer by forming the n-doping polymer and the p-doping polymer on the CNT thin film not to be spaced apart from each other.
