Touch display device and manufacturing method thereof

A manufacturing method of a touch display device comprising:

• forming a display medium layer and an electrode substrate on a driving substrate in sequence;
• bonding a flexible circuit board to a bonding area of a touch panel, wherein the flexible circuit board extends outside the touch panel;
• attaching a water-blocking adhesive layer on the flexible circuit board outside the touch panel, wherein the water-blocking adhesive layer is directly connected to a bottom surface of the flexible circuit board;
• bonding the touch panel to the electrode substrate such that the water-blocking adhesive layer is directly laminated to a top surface of the driving substrate;
• and
• filling a sealant layer on the driving substrate to seal an edge of the display medium layer, an edge of the electrode substrate, and an edge of the touch panel, wherein in a cross-sectional view;
• at the bonding area of the touch panel, the edge of the display medium layer is indented by a distance relative to the edge of the electrode substrate to form a space, and the sealant layer fills the space and is located between the water-blocking adhesive layer and the edge of the display medium layer, and there is no the sealant layer on the bottom surface of the flexible circuit board outside the touch panel;
• wherein in another cross-sectional view outside the bonding area, the sealant layer extends to cover the edge of the electrode substrate and the edge of the touch panel.
