PROBLEM TO BE SOLVED: To provide a display apparatus that transmits internal data by a multi-level signal transmission system. SOLUTION: A display apparatus includes a timing controller and a column driver. The timing controller outputs a first column clock, embedded into image data during an active period and outputs a second column clock embedded into blank data during a blank period. The column driver detects the image data using the first column clock and detects the blank data by using the second column clock. According to the display apparatus, the second column clock is embedded into the blank data, in the blank period and in a voltage level substantially the same as the voltage level of the image data. Consequently, errors are prevented which are caused by the ripple component of an analog power supply voltage generated in the blank period, in a process of restoring the embedded second column clock by the column driver.
