Abstract

The flexible display module can be curled, and may comprise: a flexible display panel having a display side and a rear side which are provided opposite to each other in a thickness direction of the flexible display panel; a first functional film layer, formed on a display side of the flexible display panel; and a second functional film layer, formed on the rear side of the flexible display panel. The ratio of the thickness of the second functional film layer to the thickness of the first functional film layer is 0.5 to 1.5, and the ratio of the elasticity modulus of the second functional film layer to the elasticity modulus of the first functional film layer is 0.5 to 1.5. The flexible display module is not prone to peeling, losing efficacy and the like.
