[0060] Even-numbered fan-out lines FL2 , FL4 , . . . , and FL1440 of the 1st to 1440th fan-out lines FL1 to FL1440 may be electrically connected to the 1st to 720th bypass lines CL1 to CL720 .

[0061] The 1st to 720th bypass lines CL1 to CL720 may include a first straight line portion L1 arranged between the 721st to 1440th data lines DL721 to DL1440 in the second area A2, a second straight line portion L2 arranged between the 1st to 720th data lines DL720 in the first area A1, and an intersection portion L3 intersecting the 1st to 1440th data lines DL1440 arranged in the first and second areas A1 and A2.

[0069] Therefore, the order of the data voltages output from the plurality of output channels CH1 to CH1440 of the data driving circuit 200 can be changed, and thus the arrangement of the fan-out lines FL1 to FL1440 can be simplified.
