A flexible AMOLED display device is provided, including an AMOLED screen and an image sensor. The AMOLED screen includes a flexible substrate, a TFT layer, an OLED layer and an encapsulation layer. The flexible substrate includes a fingerprint recognition area and a remaining non-fingerprint recognition area. The image sensor is correspondingly disposed in the fingerprint recognition area of the flexible substrate. The non-fingerprint recognition area of the flexible substrate adopts a dual organic layer structure, including two organic layers and an inorganic spacer layer disposed between the two organic layers. The fingerprint recognition area adopts a single organic layer structure, including only one organic layer. Therefore, the transmittance in the fingerprint recognition area is enhanced, the intensity of light received by the image sensor is increased, and the accuracy of fingerprint recognition is improved. Accordingly, the lifetime of the OLED in the area can be lengthened.
