    Abstract: A display apparatus includes a gate line, a data line, and a pixel. The pixel includes first and second pixels displaying grayscales different from each other in response to a data voltage provided through the data line. The first pixel includes a first transistor including a gate electrode connected to the gate line and a first terminal connected to the data line and a first liquid crystal capacitor connected to a second terminal of the first transistor. The second pixel includes a second transistor including a gate electrode connected to the gate line and a first terminal connected to the second terminal of the first transistor and a second liquid crystal capacitor connected to a second terminal of the second transistor.
