US Patent 11251410 Flexible display substrate and method for manufacturing the same

The present invention provides a flexible display substrate and a method for manufacturing the same. The flexible display substrate has a bending area and a display area. The flexible display substrate includes a first organic layer, multiple first grooves formed on one surface of the first organic layer, an intermediate layer covered on the other surface of the first organic layer, a second organic layer covered on the intermediate layer, multiple second grooves formed on one surface of the second organic layer away from the first grooves, a buffer layer covered on the one surface of the second organic layer, and a gate line covered on the buffer layer. The present invention can reduce stresses of the bending area, improve the damage resistance of the flexible display substrate during bending, and avoid cracks in an inorganic layer and breakage in a metal line.
