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 circuit board assembly includes a flexible circuit board including a first surface, a second surface opposite to the first surface, sensing pads on the first surface, and a connector on the second surface, a first liner which includes a first rear surface covering a portion of the first surface and a first top surface that is opposite to the first rear surface and in which a first opening passing through the first rear surface from the first top surface is defined, a second liner which includes a second rear surface covering a portion of the second surface and a second top surface that is opposite to the second rear surface and in which a second opening passing through the second rear surface from the second top surface is defined. Each of the first and second openings is spaced apart from the flexible circuit board in a plan view.
