Abstract
A display device and a power monitoring circuit. The power monitoring circuit monitors whether or not first power is ordinarily output from a power management integrated circuit (PMIC). When the first power is not ordinarily output, the power monitoring circuit outputs an error detection signal indicative of an abnormality in the PMIC to a main controller. The display device includes the power monitoring circuit. The operating state of the PMIC supplying power required for the driving of a display panel can be monitored.
