Abstract
A four color liquid crystal display (LCD) including red, green, blue, and white sub-pixels are provided. The LCD also includes a plurality of gate lines for transmitting gate signals to the sub-pixels and a plurality of data lines for transmitting data signals to the sub-pixels. The white sub-pixel is smaller than the other sub-pixels, and each of the data lines passes between adjacent two sub-pixels and includes at least one curved portion. Furthermore, the lengths of the data lines are substantially uniform.
Claims7
A liquid crystal display comprising:
- a plurality of gate lines formed on a substrate and extending in a first direction;
- a gate insulating layer formed on the gate lines;
- a semiconductor layer formed on the gate insulating layer;
- a plurality of data lines formed at least on the semiconductor layer and extending in a second direction;
- a plurality of drain electrodes formed at least on the semiconductor layer and separated from the data lines;
- and
- a plurality of first and second pixel electrodes connected to the drain electrodes and arranged in a plurality of rows,
- wherein width of the second pixel electrodes is smaller than width of the first pixel electrodes, the first and the second pixel electrodes are adjacent in the second direction, the first and second pixel electrodes adjacent to each other have boundaries that extend in the second direction and do not coincide with each other, a straight line that extends in the second direction and passes through centers of the first pixel electrodes passes through centers of the second pixel electrodes adjacent to the first pixel electrodes, and the data lines extend along the boundaries of the first and second pixel electrodes.
