Abstract: A pixel includes: a storage capacitor connected between a first power supply voltage and a gate node; a first transistor including a gate electrode connected to the gate node; a second transistor to transfer a data signal to a source of the first transistor in response to a scan signal; a third transistor to diode-connect the first transistor in response to the scan signal, and including first and second sub-transistors serially connected between the gate node and a drain of the first transistor; a fourth transistor to transfer an initialization voltage to the gate node in response to an initialization signal, and including third and fourth sub-transistors serially connected between the gate node and the initialization voltage; and an organic light emitting diode including a cathode connected to a second power supply voltage. At least one of the second and fourth sub-transistors includes a bottom electrode.

Abstract: A display device includes: a display unit including scan lines, data lines, unit areas corresponding to intersections of the scan lines and the data lines, the unit areas including first unit areas in an effective display area, second unit areas in a dummy area around the effective display area, some of the second unit areas being smaller than the first unit areas, and pixels in the first unit areas; a timing controller configured to receive first data including image data corresponding to the first and second unit areas and to convert the first data into second data corresponding to the effective display area; and a data driver configured to generate a data signal corresponding to the second data. The display unit includes a first horizontal line having fewer pixels than the number of the data lines.
