    Abstract: A display panel includes a source-pad portion, a first source fan-out portion and source lines. The source-pad portion has a group of pads to which a driving signal is applied from an external source. The source fan-out portion has output lines that are extended from the group of pads and are formed to have an asymmetric structure. The source lines are extended from the output lines, and pixels of different colors are connected to each of the source lines. Accordingly, a unit pixel portion is formed to be perpendicular to each other and a fan-out portion is formed to have the asymmetric structure, so that a size of a printed circuit board is remarkably decreased. Thus, costs for manufacturing a display apparatus may be decreased.
