Discussed are a display panel and a display device having the same. The display panel includes a plurality of subpixels. A gate line, a data line, and a reference voltage line are further disposed on the display panel. A gate driving circuit supplies a scan signal to the gate line. A data driving circuit converts image data into a data voltage and supplies the data voltages to the data line. A timing controller controls the gate driving circuit and the data driving circuit and generates compensation data for the image data using a sensing voltage detected through the reference voltage line. The display panel includes a plurality of sensing transistors disposed around a corresponding subpixel among the plurality of subpixels to connect the data line and the reference voltage line.
