Abstract

A flexible substrate and a manufacturing method thereof are provided according to embodiments of the present application. The flexible substrate includes a hard layer, an organic functional layer and a backplane layer which are stacked. The organic functional layer is attached to the backplane layer. A POL layer and a TP layer are included between the hard layer and the organic functional layer, and the TP layer includes a glass substrate and a conductive layer coated on a surface of the glass substrate.

Claims (28)
