Liquid crystal display device and electronic device

A liquid crystal display device comprising:

• a display portion controlled by a driver circuit and including a normally black mode liquid crystal;
• and
• a timing controller configured to control the driver circuit,
• wherein the timing controller is supplied with an image signal for displaying a moving image and an image signal for displaying a still image, and
• wherein an absolute value of a voltage applied to the normally black mode liquid crystal in order to express white in an image corresponding to the image signal for displaying the still image is larger than an absolute value of a voltage applied to the normally black mode liquid crystal in order to express white in an image corresponding to the image signal for displaying the moving image.

A liquid crystal display device comprising:

• a display portion controlled by a driver circuit and including a normally white mode liquid crystal;
• and
• a timing controller configured to control the driver circuit,
• wherein the timing controller is supplied with an image signal for displaying a moving image and an image signal for displaying a still image, and
• wherein an absolute value of a voltage applied to the normally white mode liquid crystal in order to express black in an image corresponding to the image signal on the display portion is increased as a gray level number of the image signal is smaller.

A liquid crystal display device comprising:

• a display portion controlled by a driver circuit and including a normally white mode liquid crystal;
• and
• a timing controller configured to control the driver circuit,
• wherein the timing controller is supplied with a first image signal with a first gray level number for displaying a still image and a second image signal with a second gray level number for displaying a still image, and
• wherein by the timing controller, an absolute value of a voltage applied to the normally white mode liquid crystal in order to express black in an image corresponding to the first image signal on the display portion is made smaller than an absolute value of a voltage applied to the normally white mode liquid crystal in order to express black in an image corresponding to the second image signal with the second gray level number smaller than the first gray level number.
