Abstract
A liquid crystal display device includes a liquid crystal display panel having a pixel defined by at least three sub-pixels including a blue sub-pixel, a backlight which emits, toward the liquid crystal display panel, light that brings a color temperature to a predetermined level when the pixel displays white, and a color tone correction circuit which corrects a color tone of a color displayed by the pixel. When the pixel displays a color containing at least one predetermined color component that is other than a white component and a blue component, the color tone correction circuit performs a correction to set a luminance of the blue sub-pixel lower than an original luminance.

22. A liquid crystal display device, comprising:
-
a liquid crystal display panel which includes a pixel defined by at least three sub-pixels including a blue sub-pixel; a backlight arranged to emit, toward the liquid crystal display panel, light that brings a color temperature to a predetermined level when the pixel displays white; and a color tone correction section arranged to correct a color tone of a color displayed by the pixel;
whereinwhen the pixel displays a color containing at least one predetermined color component that is other than a white component and a blue component, the color tone correction section makes a correction to set a luminance of the blue sub-pixel lower than an original luminance. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A liquid crystal display device comprising a pixel that is defined by at least three sub-pixels including a blue sub-pixel,
wherein a maximum luminance of the blue sub-pixel that is set when the pixel displays an arbitrary color containing at least one predetermined color component that is other than a white component and a blue component is lower than a luminance of the blue sub-pixel that is set when the pixel displays at least one of white and blue.
- 40. A liquid crystal display device comprising a pixel containing a red sub-pixel, a green sub-pixel, and a blue sub-pixel, wherein a luminance of the blue sub-pixel that is set when the pixel displays magenta and a luminance of the blue sub-pixel that is set when the pixel displays cyan are lower than a luminance of the blue sub-pixel that is set when the pixel displays white.
