Abstract:
1. A liquid crystal display device including a pixel formed by a liquid crystal disposed between a first substrate on which a first electrode is formed and a second substrate on which a second electrode is formed, and a light source controller having a first terminal and controlling red, green, and blue lights to be sequentially transmitted through the pixel, the liquid crystal display device comprising: a first red light emitting diode (LED) having a first terminal and a second terminal, the first terminal being coupled to the first terminal of the light source controller; a second red LED having a first terminal coupled to the second terminal of the first red LED; a first green LED having a first terminal coupled to the first terminal of the light source controller; and a blue LED having a first terminal coupled to the first terminal of the light source controller, wherein a first voltage applied by the light source controller to emit the first and second red LEDs, a second voltage applied by the light source controller to emit the first green LED, and a third voltage applied by the light source controller to emit the blue LED have almost the same or similar voltage levels.
