Abstract: A touch panel, a method for testing the touch panel and a display device are provided. In order to test the touch panel, all touch electrodes are connected in series to obtain a branch during the testing phase, a test signal is inputted to the branch, and a feedback signal outputted by the branch is analyzed for determination. All the touch electrodes are isolated from each other during a phase rather than the testing phase. Therefore, whether a touch electrode is abnormal is determined by controlling all the touch electrodes to be connected in series during the testing phase and isolated from each other during the phase rather than the testing phase, to improve efficiency for testing a touch electrode and simplifying the process of testing the touch electrode.
