Abstract

一种显示面板及其制造方法。该显示面板具有显示侧和非显示侧，包括显示区域(AA)和位于显示区域(AA)一侧边的弯折区域(B)，弯折区域(B)包括至少一条第一走线(101)，弯折区域(B)能可工作地从显示侧弯折到非显示侧，显示区域(AA)包括第二走线(102)，第一走线(101)的第一端(1011)电连接第二走线(102)，第一走线(101)的第二端(1012)通过弯折区域(B)弯折到非显示侧。弯折区域(B)还包括与第一走线(101)并列排布的检测走线(103)，检测走线(103)的至少部分随弯折区域(B)弯折，检测走线(103)包括第一端(1031)和第二端(1032)，用于连接外部检测电路，检测走线(103)和弯折区域(B)仅位于上述侧边的远离显示区域(AA)的一侧。通过外部检测电路对检测走线(103)进行检测，可以判断弯折区域(B)中与检测走线(103)并列排布的第一走线(101)的状态。
