请参阅图8，所述多个LED灯贴片105与所述柔性电路板104之间还设有反光层107，以使所述多个LED灯贴片105的部分光线投射至所述反光层107，经所述反光层107反射后从所述柔性屏101射出。所述反光层107可以为设于所述柔性电路板104上的金属涂层，所述反光层107可以涂覆于所述柔性电路板104的部分区域，以避开所述柔性电路板104上的电子线路和LED灯贴片105，以防止所述柔性电路板104上的电子线路和LED灯贴片短路。
请参阅图9，其他实施方式中，所述柔性电路板104可以为透明材质，所述反光层107可以设于所述柔性电路板104背离所述多个LED灯贴片105的表面。

进一步地，所述柔性支撑件101的材质为导光材质。所述柔性支撑件101可以作为面光源103的导光板，无需再另设置导光板，可以减少发光装置101的厚度及减少发光装置101的结构组成，从而减少发光装置101的制作成本。
请参阅图11及图12，一种实施方式中，所述柔性屏支撑件102包括相对设置的第一端1021和第二端1022，所述柔性屏支撑件102弯曲过程使得所述第一端1021和所述第二端1022相互靠近，所述第一端1021和所述第二端1022分别设有相匹配的卡合件1023，以使所述第一端1021和所述第二端1022相卡合。具体为，所述卡合件1023包括设于所述第一端1021的卡扣1024和设于所述第二端1022的卡勾1025，所述卡扣1024与所述卡勾1025相卡合，以便于所述发光装置100可佩戴至手腕上，以免手拿所述发光装置100时，遮挡所述柔性屏101上部分发光面。同时将所述发光装置100可佩戴至手腕以照亮，无需手持，增加该发光装置100便携性。在其他实施方式中，所述卡合件1023还可以是磁吸结构或其他的卡合结构，本申请不做限制。
