Abstract
A liquid crystal display device that can reduce picture quality deterioration due to a kickback voltage and can accurately detect a kickback voltage is provided. The liquid crystal display device includes: a liquid crystal panel including a detector configured to generate a kickback voltage detection signal, a detection line for supplying the kickback voltage detection signal, and a ground pattern along and adjacent to one side of the detection line; and a common voltage generator connected to the detection line and configured to generate a common voltage corresponding to the kickback voltage detection signal and to supply the generated common voltage to the liquid crystal panel.
Claims7
A liquid crystal display device comprising:
- a liquid crystal panel comprising:
- a detector configured to generate a kickback voltage detection signal;
- a first substrate;
- a second substrate facing the first substrate;
- a liquid crystal layer between the first substrate and the second substrate;
- and
- a sealing pattern adhering the first substrate to the second substrate and sealing the liquid crystal layer in a first direction along one side of the liquid crystal display, the first direction being a lengthwise direction of the one side, the sealing pattern defining a contact portion on the one side extending lengthwise in the first direction;
- a detection line for supplying the kickback voltage detection signal, the detection line extending lengthwise in the first direction at a region corresponding to the contact portion;
- and
- a ground pattern along and adjacent to one side of the detection line and extending lengthwise and contacting the sealing pattern in the first direction along the contact portion between the first substrate and the sealing pattern and
- a common voltage generator connected to the detection line and configured to generate a common voltage corresponding to the kickback voltage detection signal and to supply the generated common voltage to the liquid crystal panel.
