Display device and manufacturing method thereof

The invention discloses a display device and a manufacturing method thereof. The display device comprises a driving substrate, an electronic ink layer and a conductive waterproof layer. The electronic ink layer is arranged on the driving substrate. And the conductive water-blocking layer is arranged on the electronic ink layer. The conductive and waterproof layer comprises a conductive layer, a waterproof layer and a substrate layer. The conductive layer is located between the waterproof layer and the electronic ink layer, and the conductive layer is separated from the electronic ink layer. According to the display device, the conductive water-blocking layer with the effects of resisting UV, blocking water and driving the electronic ink layer is arranged, so that the display device does not need to be provided with a protective film covering the surface, back to the electronic ink layer, of the conductive water-blocking layer and the side wall of the conductive water-blocking layer, and the thickness of the d
