Abstract: Disclosed are a flexible display screen and a flexible display device. The flexible display screen includes a flexible display panel and a driver chip, the flexible display panel includes a support portion, a first heat insulation layer, a heat dissipation layer, and a second heat insulation layer which are arranged in sequence along a direction from back to a light-emitting surface, the support portion is provided with a recess, and the driver chip is received in the recess.

Abstract: A display panel includes a first substrate, a light-emitting functional layer, a second substrate, an optical adhesive layer and a polarizer stacked in sequence. The display panel includes a display area and a non-display area. The display panel further includes a touch-control driving plate disposed on a surface of a first portion of the second substrate facing away from the light-emitting functional layer. The first portion of the second substrate is in the non-display area. The optical adhesive layer covers a second portion of the touch-control driving plate. A distance between a surface of the optical adhesive layer facing away from the light-emitting functional layer and the light-emitting functional layer is greater than or equal to a distance between a surface of the touch-control driving plate facing away from the light-emitting functional layer and the light-emitting functional layer.
