Abstract
According to one embodiment, an RGB image signal is output from a driver, first ends of a first open-close signal line and a second open-close signal line are each connected to the driver and second ends of the first open-close signal line and the second open-close signal line are free. Power is supplied to a signal selection circuit, which selects a signal line and outputs a polarity inverted image signal, via the first open-close signal line and the second open-close signal line.
Claims16
A display device, comprising:
- a first insulating substrate;
- a plurality of gate lines in a display region on the first insulating substrate;
- a plurality of signal lines in the display region, the plurality of signal lines being orthogonal to the plurality of gate lines;
- pixel including switching elements at respective positions where the plurality of gate lines and the plurality of signal lines intersect and pixel electrodes connected to the switching elements;
- a driver configured to output an image signal;
- a signal selection circuit configured to distribute the image signal output from the driver to the signal line connected to the pixel;
- a first open-close signal line configured to supply a first open-close signal from the driver to the signal selection circuit;
- and
- a second open-close signal line configured to supply a second open-close signal from the driver to the signal selection circuit, the second open-close signal having a pole different from the first open-close signal;
- a first end of the first open-close signal line being connected to the driver and a second end of the first open-close signal line being free;
- and
- a first end of the second open-close signal line being connected to the driver and a second end of the second open-close signal line being free.
