The present invention relates to a polymer electrolyte composition, and an electrochromic device using the same. The polymer electrolyte composition comprises: a) a thermosetting precursor mixture; b) a UV crosslinkable polymer including a siloxane-based resin; c) a thermosetting catalyst; d) a UV catalyst; e) an ion salt; and f) a solvent. The polymer electrolyte composition according to an embodiment of the present invention is a UV-thermosetting electrolyte composition, which can be patterned by using a difference in ion conductivity which varies depending on the degree of hardening, and at the same time, can be filled with electrolytes, thereby being useful in various types of electrochemical devices. 본 발명은 a) 열경화형 전구체 혼합물; b) 실록산계 수지를 포함하는 UV 가교성 고분자; c) 열경화 촉매; d) UV 촉매; e) 이온염; 및 f) 용매를 포함하는 고분자 전해질 조성물, 및 이를 이용한 전기변색소자에 관한 것이다. 본 발명의 일 실시예에 따른 고분자 전해질 조성물은 UV-열경화형 전해질 조성물로서, 경화도에 따라 달라지는 이온전도도 차이를 이용하여 패터닝이 가능하고(patternable), 이와 동시에 전해질 충진이 가능하여, 다양한 형태의 전기화학소자에 유용하게 사용될 수 있다.
