Abstract
A polymer material includes a segment of an alternating copolymer of a structural unit of a specific structure and has a glass transition temperature of greater than or equal to about 50° C. and less than or equal to about 250° C. The polymer material is capable of improving luminescence life-span of an electroluminescence device, particularly a quantum dot light emitting device.
