9. A tiled display device comprising:
display devices; and
a connection member between the display devices,
wherein one display device among the display devices comprises:
PWM data lines for respectively receiving PWM data voltages;
first to third data lines for respectively receiving first to third data voltages;
sub-pixels respectively connected to the PWM data lines, respectively connected to the first to third data lines, and comprising at least one light-emitting element;
a first power supply line connected to a first electrode of the at least one light-emitting element, and for receiving a first power supply voltage;
a global power supply line for receiving a global power supply voltage; and
a first demultiplexer between the PWM data lines and the global power supply line,
wherein the PWM data voltages comprise grayscale voltages ranging from a black grayscale voltage to a white grayscale voltage, and
wherein a voltage difference between the global power supply voltage and the black grayscale voltage is less than a voltage difference between the global power supply voltage and the first power supply voltage.
