Abstract
A touch panel and a manufacturing method thereof, and a display device. An insulation layer (4) positioned between a substrate (1) and a polarizer (3) is configured to comprise a silicon nitride layer (41) and a barrier layer (42) positioned at one side of the silicon nitride layer (41) away from the substrate (1). The barrier layer (42) can serve as a covering layer that stops an ammonia gas escaped from the silicon nitride layer (41) from moving to the polarizer (3) so as to prevent fading of the polarizer. The insulation layer (4) is configured to comprise two thin layers, namely a silicon nitride layer (41) and a barrier layer (42).
