    Abstract: A display panel includes a 1-1st sub-pixel and a 1-2nd sub-pixel disposed in a first row, a 2-1st sub-pixel disposed in a second row and a 3-1st sub-pixel and a 3-2nd sub-pixel disposed in a third row. A first data line extends from the first row to the third row and electrically connects a pixel circuit of the 1-1st sub-pixel, a pixel circuit of the 2-1st sub-pixel, and a pixel circuit of the 3-1st sub-pixel. A 2-1st data line is electrically connected to a pixel circuit of the 1-2nd sub-pixel. A 2-2nd data line is electrically connected to a pixel circuit of the 3-2nd sub-pixel. A first bridge line is disposed on a different layer than the data lines and contacts the 2-1st data line and the 2-2nd data line and includes an overlapping portion extending along at least a portion of the first data line.
