Abstract
A display panel including pixels and a circuit board electrically connected to the display panel, wherein the circuit board includes: a base film having a first area overlapping at least a portion of a connector and a second area spaced apart from the connector; and a unit signal line disposed on the base film, electrically connected to the connector, and having a first characteristic impedance in the first area and a second characteristic impedance in the second area, the second characteristic impedance being smaller than the first characteristic impedance.
