Abstract
A liquid crystal display device includes a reflective liquid crystal display panel and a panel driver configured to generate a driving voltage to drive the reflective liquid crystal display panel. The panel driver generates grayscale voltages having a voltage level between a first voltage and a second voltage based on a driving voltage-reflection ratio property in which a reflection ratio increases when the driving voltage increases to the first voltage and the reflection ratio decreases when the driving voltage increases from the first voltage to the second voltage.
