Fabricating method of flexible display and flexible display

A fabricating method of a flexible display, comprising:

• forming a release layer on a carrier substrate;
• patterning the release layer to form a patterned release layer;
• forming a flexible substrate on the patterned release layer, the flexible substrate covering the patterned release layer and contacting a lateral side of the patterned release layer and a portion of the flexible substrate contacting the carrier substrate, wherein an adhesive force between the patterned release layer and the flexible substrate is larger than an adhesive force between the patterned release layer and the carrier substrate, and the flexible substrate is a single layer;
• forming a device layer on the flexible substrate;
• forming a display layer on the device layer;
• simultaneously cutting the flexible substrate and the patterned release layer;
• and
• separating the patterned release layer being cut from the carrier substrate, wherein the flexible substrate, the device layer, and the display layer which have been cut are sequentially disposed on the patterned release layer being separated.
