Abstract: The present invention relates to a display panel and an electronic display device. A first source of a driving thin film transistor extends and covers a first gate layer, the first source is used to block water vapor, thus to prevent water vapor intrusion from reducing weather resistance of the driving thin film transistor, to improve a service life of the driving thin film transistor, and to prevent a degradation or a failure of display qualities caused by a decline during use of the driving thin film transistor, and to improve display stability of the display panel.
