Abstract
In pixels included in a display panel of an light emitting diode display, each pixel on an nth pixel row, where n is a natural number, includes a light emitting diode including an anode electrode connected to a node C and a cathode electrode connected to an input terminal of a low potential driving voltage, a driving TFT including a gate electrode connected to a node A, a drain electrode connected to a node B, and a source electrode connected to a node D, a first TFT connected between the node A and the node B, a second TFT connected to the node C, a third TFT connected between a data line and the node D, a fourth TFT connected between an input terminal of a high potential driving voltage and the node B, and a fifth TFT connected between the node D and the node C.
