所述背板层20位于所述支撑层10上,所述背板层20包括第一背板201和第二背板202。
对于现有的柔性基板30,由于需要将连接有柔性电路板的部分面板弯折至面板内侧,以减少电子设备的下边框,增加屏占比。而为了保证柔性面板的弯折性能,弯曲区303对应的背板通过需要去除。因此,所述第一背板201和所述第二背板202之间包括断差。该断差区域对应于所述柔性基板30的弯曲区303,以减小所述柔性基板30的弯曲应力;
所述背板层20在所述柔性基板30的正投影位于所述柔性基板30内。即所述柔性基板30的面积大于所述背板层20的面积。
所述柔性基板30位于所述背板层20上。所述柔性基板30包括用于设置像素阵列的第一区301、第二区302以及连接所述第一区301和所述第二区302之间的弯曲区303。所述第一区301对应于所述第一背板201,所述第二区302对应于所述第二背板202。
