ABSTRACT:
A photoluminescence polymer having a repeating unit in which an aromatic amine and a double bond are conjugated. The photoluminescence polymer can be used as an emission material for the display device, which is particularly useful in a display device requiring an film forming property. Also, a device having the photoluminescence polymer has a low driving voltage and a short response time, and can display various colors over a range from blue to green, especially, blue.
