Power supply unit and display device including the same

A display device, including:

• a display panel including a plurality of gate lines, a plurality of data lines, and a plurality of pixels formed at respective intersections of the gate lines and the data lines;
• a data driver including a plurality of first source drive ICs and a plurality of second source drive ICs, the first and the second source drive ICs being configured to output data voltages to the plurality of data lines;
• and
• a power supply unit, including:
• a first voltage generator for generating a first voltage;
• a first voltage line connected to the first voltage generator for supplying the first voltage to the plurality of first source drive ICs;
• a second voltage generator for generating a second voltage, the second voltage generator being separate from the first voltage generator;
• a second voltage line connected to the second voltage generator for supplying the second voltage to the plurality of second source drive ICs;
• and
• at least one diode connected between the first voltage line and the second voltage line, the at least one diode allows a current flow from the first voltage line to the second voltage line if a difference between the first voltage of the first voltage line and the second voltage of the second voltage line is greater than a first predetermined voltage.
