Claim:
1. A display panel comprising: a plurality of scan lines extending in a first direction; a plurality of data lines extending in a second direction that crosses the first direction; a plurality of organic light emitting diodes; a plurality of pixel circuits respectively corresponding to the plurality of organic light emitting diodes, configured to respectively supply drive currents, and respectively electrically coupled to the plurality of scan lines and the plurality of data lines; a plurality of repair pixel circuits configured to generate repair drive currents when there is a malfunctioning pixel circuit among the plurality of pixel circuits; a plurality of repair lines; and a plurality of repair data lines, wherein a corresponding repair pixel circuit of the repair pixel circuits corresponds to the malfunctioning pixel circuit, and is configured to generate the repair drive current based on a repair data voltage from a corresponding repair data line of the plurality of repair data lines that corresponds to the malfunctioning pixel circuit, wherein the repair drive current is configured to be supplied to a corresponding organic light emitting diode of the plurality of organic light emitting diodes that corresponds to the malfunctioning pixel circuit through a corresponding repair line of the plurality of repair lines that corresponds to the malfunctioning pixel circuit, and wherein a length of a portion of the plurality of repair data lines that extends in the first direction is greater than a length of a portion that does not extend in the first direction.
