Flexible display device and manufacturing method thereof

A flexible display device, comprising:

• a thin-film transistor (TFT) array substrate having a first surface;
• an integrated circuit located on the first surface of the TFT array substrate;
• a front panel laminate located on the first surface of the TFT array substrate;
• a first protection sheet covering the front panel laminate and the first surface of the TFT array substrate, and having an opening, wherein the integrated circuit is in the opening;
• and
• a waterproof glue located in the opening and surrounding the integrated circuit.

A manufacturing method of a flexible display device, comprising:

• forming a through hole in a first protection sheet;
• adhering the first protection sheet to a first surface of a thin-film transistor (TFT) array substrate on which a front panel laminate and a flexible printed circuit board are disposed, wherein a portion of the flexible printed circuit board and a portion of the TFT array substrate are located in the through hole;
• and
• filling a waterproof glue in the through hole to cover the portion of the flexible printed circuit board and the portion of the TFT array substrate.
