摘要:
In a liquid crystal display device capable of performing image display while keeping a background in a transparent state, field-sequential driving is performed without causing color mixing.A backlight (700) is configured by upper-side LEDs (71U) and lower-side LEDs (71D) that are provided respectively in an upper side and a lower side of a liquid crystal panel (800), and an upper-side light guide plate (72U) and a lower-side light guide plate (72D) for guiding emission light respectively from the upper-side LEDs (71U) and the lower-side LEDs (71D) to the liquid crystal panel (800). When a screen of a color corresponding to each field which constitutes one frame period is displayed, LEDs included in the upper-side LEDs (71U) are turned into a light emission state and then LEDs included in the lower-side LEDs (71D) are turned into the light emission state, and the LEDs included in the upper-side LEDs (71U) are turned into a light-off state and then the LEDs included in the lower-side LEDs (71D) are turned into the light-off state.
