Abstract
A flexible polarizer and a flexible touch display device. The flexible polarizer includes: a support protective layer; a linear polarized layer provided on the side of the support protection layer and comprising an acidic substance; a retardation layer provided on the side of the linear polarized layer distant from the support protection layer, and bonded to the linear polarized layer by means of a first bonding layer; and a block layer provided on the side of the retardation layer distant from the linear polarized layer. The block layer is bonded to a flexible touch display panel of the flexible touch display device by means of the second bonding layer. The block layer is used for blocking the acidic substance in the linear polarized layer from permeating into the flexible touch display panel.
