[ 22. A display device, comprising:
a scan driver configured to apply scan signals to a plurality of scan lines;
a data driver configured to apply data signals to a plurality of data lines;
a plurality of first pixels disposed in a first column, configured to display a first color, and electrically connected to a first data line of the data lines;
a plurality of second pixels disposed in the first column, configured to display a second color, and electrically connected to the first data line of the data lines;
a plurality of third pixels disposed in a second column, configured to display a third color, and electrically connected to a second data line of the data lines; and
a lighting tester comprising:
a first transistor including an end electrically connected to the first data line;
a second transistor including an end electrically connected to the first data line;
a third transistor including an end electrically connected to the second data line;
a first interconnection connected to another end of the first transistor;
a second interconnection connected to another end of the second transistor;
a third interconnection connected to another end of the third transistor;
a first control interconnection connected to a gate of the first transistor;
a second control interconnection connected to a gate of the second transistor; and
a third control interconnection connected to a gate of the third transistor,
wherein the first interconnection is configured to supply a first voltage, the second interconnection is configured to supply a second voltage, and the third interconnection is configured to supply a third voltage,
wherein the first control interconnection is configured to supply a first control signal, the second control interconnection is configured to supply a second control signal, and the third control interconnection is configured to supply a third control signal,
wherein the lighting tester is disposed outside of an area where the first, the second, and the third pixels are disposed,
wherein both of the first voltage and the second voltage are supplied to the first column through the first data line, and
wherein each of the first voltage, the second voltage, and the third voltage is supplied from test power sources for lighting the first and second columns.]
