Abstract

A liquid crystal display device includes a liquid crystal layer between first and second substrate. The first substrate includes a first and second sub-pixel areas. A first sub-pixel electrode is on the first substrate in the first sub-pixel area, and a first transistor is connected to a gate line, data line, and first sub-pixel electrode on the first substrate. A second sub-pixel electrode is on the first substrate in the second sub-pixel area, and a second transistor is connected to the gate line, the first transistor, and the second sub-pixel electrode. A first storage line is adjacent to one side of the first sub-pixel electrode. A second storage line is spaced from the first storage line and is adjacent to one side of the second sub-pixel electrode. A third transistor is connected to the gate line, second transistor, and second storage line.
