Abstract: A flexible display panel may include a flexible base substrate. The flexible base substrate may include a bendable region (2). The flexible display panel may further include a first layer on the flexible base substrate; a trench (26) penetrating at least part of the first layer; a second layer (14) in the trench; and a metal layer (24) on the second layer. The second layer may have a smaller elastic modulus than the first layer. At least part of the second layer and the metal layer may be conformal with the bendable region during bending of the bendable region.
