The flexible substrate has a first surface and a second surface, disposed opposite to each other. The array circuit layer is disposed on the second surface of the flexible substrate. The protection film is disposed on the first surface of the flexible substrate. The adhesive layer is disposed between the protection film and the flexible substrate, and has a thickness, substantially greater than or equal to 30 micrometers. ## Claims ### Claim 1 A flexible display, comprising: a flexible substrate, having a first surface and a second surface opposite to each other; an array circuit layer, disposed on the second surface of the flexible substrate; a first protection film, disposed on the first surface of the flexible substrate; and a first adhesive layer, disposed between the first protection film and the flexible substrate, and the first adhesive layer having a thickness substantially greater than or equal to 30 micrometers (μm). ### Claim 2 (depends on 1) The flexible display of claim 1, wherein the first adhesive layer directly contact the flexible substrate. ### Claim 3 (depends on 1) The flexible display of claim 1, further comprising: a display media layer, disposed on the array circuit layer; and a second protection film, disposed on the display media layer. ### Claim 4 (depends on 3) The flexible display of claim 3, wherein an area of the first protection film is substantially larger than an area of the flexible substrate, and the flexible display further comprises a first water-resisting layer disposed on a side of the first protection film facing the first adhesive layer, the first water-resisting layer covering a sidewall of the first adhesive layer, a sidewall of the flexible substrate, a sidewall of the array circuit layer, a sidewall of the display media layer and a sidewall of the second protection film. ### Claim 5 (depends on 3) The flexible display of claim 3, wherein an area of the second protection film is substantially larger than an area of the flexible substrate, and the flexible display further comprises a first water-resisting layer disposed at a side of the second protection film facing the display media layer, the first water-resisting layer covering a sidewall of the first protection film, a sidewall of the first adhesive layer, a sidewall of the flexible substrate, a sidewall of the array circuit layer and a sidewall of the display media layer. ### Claim 6 (depends on 3) The flexible display of claim 3, wherein an area of the first protection film and an area of the second protection film are substantially larger than an area of the flexible substrate, and the flexible display further comprises a first water-resisting layer disposed between the first protection film and the second protection film, the first water-resisting covering a sidewall of the first adhesive layer, a sidewall of the flexible substrate, a sidewall of the array circuit layer and a sidewall of the display media layer. ### Claim 7 (depends on 1) The flexible display of claim 1, wherein the first protection film comprises a plastic material, a metal thin film or a water-resisting material. ### Claim 8 (depends on 7) The flexible display of claim 7, wherein the plastic material comprises polyethylene terephthalate (PET), polycarbonate (PC), polyethylene naphthalate (PEN), polymethylmethacrylate (PMMA) or polyimide (PI). ### Claim 9 (depends on 1) The flexible display of claim 1, further comprising a second water-resisting layer disposed between the first adhesive layer and the first protection film. ### Claim 10 (depends on 9) The flexible display of claim 9, further comprising a second adhesive layer disposed between the second water-resisting layer and the first protection film. ### Claim 11 (depends on 10) The flexible display of claim 10, wherein an area of the first protection film is substantially larger than an area of the flexible substrate. ### Claim 12 (depends on 11) The flexible display of claim 11, wherein an area of the second adhesive layer is substantially larger the area of the flexible substrate. ### Claim 13 (depends on 12) The flexible display of claim 12, wherein an area of the second water-resisting layer is substantially larger than the area of the flexible substrate. ### Claim 14 (depends on 13) The flexible display of claim 13, wherein an area of the first adhesive layer is substantially larger than the area of the flexible substrate.
