Embodiments of the present invention relate to a display device which maintains a power sequence of driving voltages or minimizes each time of the power sequence without adding components when realizing the power sequence, and a power supply unit thereof. The power supply unit comprises: a connection circuit unit for transferring high potential power voltage maintained in a first power block when a power source is off to a logic power voltage maintained in a second voltage block; and a voltage detection unit for providing a control signal to the connection circuit unit when the power source is off, and controlling an operation of the connection circuit. |
