We developed the new polymers, SKB1 and SKB2, exhibiting deep‐blue emission (CIE: x=0.145–0.148, y=0.093–0.135). The device using SKB1 demonstrated the current efficiency of 3.11 cd/A at 6.6V with 3,251 cd/m 2 , and then the CIE coordinate of the emission was x=0.147 and y=0.123. The SKB2 device showed the current efficiency of 3.70 cd/A at 6.6V with 2,930 cd/m 2 , and then the CIE coordinate of the emission was x=0.148 and y=0.135.
