The invention provides an array substrate, a display panel and a displayer. In a non-display region of the array substrate, grid lines are connected with the input ends of ESD devices, the output ends of the ESD devices are connected with electrostatic discharge lines, and between the connecting ends of every two adjacent ESD devices and every two adjacent electrostatic discharge lines, the electrostatic discharge lines are connected with public electrode lines through TFTs. When the ESD devices discharge static onto the electrostatic discharge lines, the static is discharged to the public electrode leads through a nearer TFT preferentially, therefore, the problems that due to the fact that an existing static discharge path is long, static injuries occur between grid lines and static discharge lines and a short circuit occurs are avoided, the static discharge efficiency is increased and the performance of the array substrate is improved.
