A flexible substrate, an OLED device comprising the flexible substrate, and a defect detection method thereof. The flexible substrate comprises a bottom plate and barrier layers (2, 4) disposed above the bottom plate (1). The flexible substrate further comprises a crack detection layer (3), the crack detection layer (3) is disposed adjacent to the barrier layers (2, 4), the crack detection layer (3) generates a crack when a crack occurs in the barrier layers (2, 4), and the crack detection layer (3) having a crack is different in color from the crack detection layer (3) that does not have a crack in a power-on state. By means of the flexible substrate and the OLED device, a high detection efficiency is achieved, the accuracy of a detection effect is ensured, and the product defect-free rates of the flexible substrate and the OLED device are improved. |
