Abstract: An LCD device includes: an LC panel which exhibits different gamma curves under different view angles, and a display control circuit which divides a single frame period into first and second display periods and divides a display region of the LC panel into first and second regions. The display control circuit has a luminance computing section which computes A to D so that A to D satisfies A+C=B+D and A≠B≠D as well as C≠B≠D, where A and C are gray-level luminances, A and B are the white luminances of pixel data displayed in the first and second regions, respectively, during the first display period, and C and D are the white luminances of pixel data displayed in the first and second regions, respectively, during the second display period.

Abstract: Provided is a liquid crystal display device which not only protects user's privacy but also improves a display quality of an image when a display is viewed from the front. According to a liquid crystal display device (1) in accordance with the present invention, in a first display period, a light source controlling section (5) controls a backlight (3) to emit light having a given intensity, and in order to display a given gradation in a first region which is a part of the image, a gradation voltage generating section (6) applies a voltage which is in accordance with the given gradation, and in a second display period which is different from the first display period, the light source controlling section (5) controls the backlight (3) to emit light having a lower intensity than the intensity of the given intensity of the light emitted in the first display period, and in order to display the given gradation in a second region which is different from the first region, the gradation voltage generating section (6) applies a higher voltage than the voltage applied to display the given gradation in the first region.

Abstract: In a driving method for driving a liquid crystal display device, each of frame periods is divided into a drive period in which a counter electrode is driven, and a drive suspension period in which the counter electrode is not driven. During the drive period, a data signal is outputted to a video signal line driving circuit at a frequency corresponding to a driving frequency for driving the counter electrode. During the drive suspension period, the outputting of the data signal is stopped. Thus, there are provided a liquid crystal display device and a driving method therefor, in which user aggravating sound is prevented without increasing power consumption.
