A display apparatus includes an integral integrated circuit and a display panel. The integral integrated circuit includes a gate channel which outputs a gate primitive signal and a data channel which outputs a data voltage. The display panel includes a level shifter which amplifies the gate primitive signal to generate a gate signal. The display panel is configured to display an image based on the gate signal and the data voltage. The display panel includes a first gate line extending in a first direction and a second gate line extending in a second direction. The second direction is different from the first direction. The second gate line is connected to the first gate line. The level shifter is connected to the second gate line.
