A touch panel and a manufacturing method thereof, and a display device. An insulation layer () positioned between a substrate () and a polarizer () is configured to comprise a silicon nitride layer () and a barrier layer () positioned at one side of the silicon nitride layer () away from the substrate (). The barrier layer () can serve as a covering layer that stops an ammonia gas escaped from the silicon nitride layer () from moving to the polarizer () so as to prevent fading of the polarizer. The insulation layer () is configured to comprise two thin layers, namely a silicon nitride layer () and a barrier layer ().

A method for obtaining a contact resistance of a planar device includes: obtaining a contact resistance of a planar device by using a potential measurement method, in the measurement of the surface potential distribution, the planar device is in a state of current flowing, a certain voltage drop is formed at a junction area of the device; extracting the voltage drop measured through the Kelvin microscope by using a linear fitting method; and dividing the measured voltage drop by the current flowing through the device, thereby accurately calculating the magnitude of the contact resistance at the junction area of the planar device. With the present invention, the contact resistance of the planar device can be precisely measured, which is suitable for the contact resistance measurement experiments of devices such as thin film transistors and diodes. The invention has the advantages of reasonable theory, accurate result, simple and easy operation, and is favorable for optimizing the device performance and establishing a complete electrical model of the device.
