Abstract: A liquid crystal display device in which an inversion driving scheme is applied to a pixel array which shares data lines. The liquid crystal display device varies driving waveforms of gate signals or data signals according to temperature and may suppress a color deviation of a display panel attributable to inversion of polarities of data signals. A timing controller may be configured to apply control signals to a data drive circuit and a gate drive circuit, the control signals includes a slew rate control pulse that controls the data drive circuit to vary any one of a rising slew rate and a falling slew rate of the data signal corresponding to the main charge interval of each of the gate signals.

Abstract: A display device includes a display panel, a main circuit board, a first connecting circuit board, a second connecting circuit board, and a sealing member. The display panel includes a first pad row and a second pad row. The first connecting circuit board is connected to the first pad row, and the second connecting circuit board is connected to the second pad row. The second pad row is spaced farther from an edge of the display panel than the first pad row. The sealing member is disposed between the first connecting circuit board and the second connecting circuit board to seal a gap between the first connecting circuit board and the display panel.
