description Provided are a positive electrode layer for an all-solid secondary battery, an all-solid secondary battery including the positive electrode layer, a method for preparing the positive electrode layer, in which the positive electrode layer includes a positive electrode current collector and a positive electrode active material layer disposed on the positive electrode current collector, wherein the positive active material layer includes a positive electrode active material, a binder, a sulfide-based solid electrolyte, and a dispersion medium, the dispersion medium includes a compound represented by Chemical Formula 1 and a compound represented by Chemical Formula 2, [Chemical Formula 1] R_1-C(═O)O-R_2 wherein R_1 is a C1-C2 alkyl group and R_2 is a C7-C9 alkyl group, [Chemical Formula 2] R_2-OH wherein R_2 is a C7-C9 alkyl group. The all-solid secondary battery has capacity characteristics and an improved lifespan. 황화물계 고체 전해질을 포함하는 전고체 이차전지용 양극층이며, 상기 양극층이 양극 집전체 및 상기 양극 집전체 상에 배치된 음극 활물질층을 포함하며, 상기 양극층이 양극 활물질, 바인더, 황화물계 고체 전해질 및 분산매를하기 함유하며, 상기 분산매가 화학식 1로 표시되는 화합물 및 하기 화학식 2로 표시되는 화합물을 포함하는 전고체 이차전지용 양극층. 이를 포함하는 전고체 이차전지 및 그 제조방법을 제시한다. [화학식 1] R1-C(=O)O-R2 R1은 C1-C2의 알킬기이고, R2는 C7 내지 C9의 알킬기이고, [화학식 2] R2-OH 화학식 2 중 R2는 C7 내지 C9의 알킬기이다.
