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.

Abstract: A display device includes a plurality of light emitting elements which emits a blue light; a light control layer disposed on the light emitting elements and including: a first light control part which absorb the blue light and emits a red light; a second light control part which absorbs the blue light and emits a green light; and a third light control part which transmits the blue light; and a light selective filter disposed on the light control layer. The light selective filter includes a liquid crystal filter and a color filter. The liquid crystal filter transmits red light and green light and blocks blue light. The color filter is absorbs the red light and the green light and transmits the blue light.
