技术领域
本公开涉及显示技术领域，特别涉及一种柔性显示装置。
背景技术
柔性显示屏整体上是由一些膜材堆叠而成，强度比较弱，柔性显示屏中的盖板的厚度也很薄，因此在用户使用的过程中触感略差。
另外，柔性显示屏经常在折叠状态和展开状态两个不同的操作模式之间切换。在从柔性显示屏从折叠状态变到展开状态时，由于柔性显示屏的膜材的恢复能力较差，因此柔性显示屏上的与转轴对应的折叠位置处会出现凸起。
综上所述，现有技术中的柔性显示屏存在使用过程中折叠位置处凸起的问题，导致触感不佳。

在一些实施方式中，壳体2的主体结构21上设置有转轴3，位于转轴3一侧的第一部分围绕转轴3相对于位于转轴3另一侧的第二部分转动以实现壳体2的弯折。当然，第一部分和第二部分均可相对于转轴转动。
在另一些实施方式中，壳体2的背面为一整面板状设置，不设置转轴，在弯折区的材质可弯折，如采用铜或其他材质的金属。
柔性显示屏1的背面设置有支撑层4，支撑层4位于柔性显示屏1的背面与主体结构21之间。示例性地，支撑层4至少部分设置在柔性显示屏1的弯折区。示例性地，支撑层4设置在柔性显示屏1的弯折区并延伸到非弯折区。
