发明名称 SEMI-TRANSMISSIVE LIQUID CRYSTAL DISPLAY DEVICE
摘要 PROBLEM TO BE SOLVED: To suppress reduction in contrast due to light scattering, or the like, in a reflection pixel portion, and to reduce power consumption, in a liquid crystal display device capable of displaying a moving image and a still image.SOLUTION: In an image signal writing period, a first image signal is supplied to a first liquid crystal element and a first capacitor from a first signal line. In a backlight lighting period, display is performed in a light-transmitting pixel portion, in response to the first image signal. In a black gray scale signal writing period, in the reflective pixel portion, a signal for black display is supplied to a second liquid crystal element and a second capacitor from a second signal line. In a still image signal writing period, a second image signal is supplied to the first liquid crystal element, the first capacitor, the second liquid crystal element, and the second capacitor from the first signal line, and in a still image signal holding period, display is performed in the reflective pixel portion, in response to the second image signal.
