Abstract
The present disclosure provides a composite film including a hydrophobic film layer and a hydrophilic film layer, a manufacture method thereof, and a light-emitting display device. The hydrophobic film layer is in contact with the hydrophilic film layer, and the hydrophilic film layer forms folds under an action of water vapor. As such, it is possible to achieve real-time detection of whether water vapor enters a light-emitting display device formed subsequently, and thus the adverse effects of water vapor on the light-emitting display device can be eliminated timely.
