Provided are a detection method and a detection device, the detection method includes: in a first writing stage, providing an active voltage to each data line, each power supply terminal, both ends of a first gate line to-be-detected, an absolute value of the active voltage of each data line is smaller than that of the active voltage of the power supply terminal, an absolute value of the active voltage of the first gate line to-be-detected is smaller than that of the active voltage of each data line; in a first detection stage, maintaining the active voltage of the power supply terminal, providing an inactive voltage to the first gate line to-be-detected and providing an active voltage to the data line, detecting voltages at second electrodes of storage capacitors corresponding to the first gate line to-be-detected, determining whether the first gate line to-be-detected has breakpoint according to the detected voltages.
