Abstract
Embodiments of the present invention provide a gas detection sensor, a display panel, and a display device. The gas detection sensor comprises: a gas sensitive part; two detection electrodes electrically connected with each other through the gas sensitive part; and a protective layer enclosing the gas sensitive part and the detection electrodes. When one of the detection electrodes is applied with a detecting signal, the detecting signal is output from the other detection electrode after being modulated by the gas sensitive part, and a voltage signal output by the other detection electrode is related to a nature of the outside air to which the gas sensitive part is exposed, thereby a detection on air quality may be achieved through detecting the voltage signal output from the other detection electrode, such that a simply structured and portable gas detection sensor can be realized.
