A flexible display module includes a cover, a flexible display panel, a rigid backplane component, and an optical device that are sequentially disposed. The optical device is disposed on a side of the rigid backplane component and is away from the flexible display panel. The rigid backplane component includes a rigid backplane body and a rigid light-transmitting component. The rigid light-transmitting component is disposed between the optical device and the flexible display panel, and the rigid light-transmitting component has a light transmission feature and is rigid.
