Abstract

Provided is a liquid crystal display to provide improved transmittance and visibility includes a first substrate; a first switching element and a second switching element formed on the first substrate configured to be switched by the same signal; a first subpixel electrode connected to the first switching element; a second subpixel electrode connected to the second switching element; a third switching element connected to the second switching element; a third subpixel electrode connected to the third switching element; a second substrate; a common electrode formed on the second substrate; and a liquid crystal layer formed between the first substrate and the second substrate.

Claims (19)

1. A liquid crystal display, comprising:

a first substrate;

a first gate line, a second gate line, and a data line formed on the first substrate;

a first switching element and a second switching element connected to the first gate line and the data line;

a first subpixel electrode connected to the first switching element;

a second subpixel electrode and a third subpixel electrode connected to the second switching element;

a first transforming capacitor formed between the second switching element and the third subpixel electrode;

a third switching element connected to the second switching element and configured to be switched by a signal received from the second gate line;

a second transforming capacitor connected to the third switching element;

a second substrate;

a common electrode formed on the second substrate; and

a liquid crystal layer formed between the first substrate and the second substrate,

wherein the first switching element is directly connected to the data line.

2. The liquid crystal display of claim 1 , wherein, in response to the third switching element being switched by the signal received from the second gate line, the voltage of the first subpixel electrode is higher than the voltage of the second subpixel electrode, and

the voltage of the second subpixel electrode is higher than the voltage of the third subpixel electrode.

3. The liquid crystal display of claim 2 , wherein a voltage ratio of the first subpixel electrode to the second subpixel electrode is 1:0.6-0.85, and

a voltage ratio of the first subpixel electrode to the third subpixel electrode is 1:0.4-0.7.

4. The liquid crystal display of claim 2 , wherein an area ratio of the first subpixel electrode to the second subpixel electrode is 1:1-2, and

an area ratio of the first subpixel electrode to the third subpixel electrode is 1:1-2.
