Abstract
The present invention provides a liquid crystal display device in which a decrease in primary color luminance, a decrease in chroma and an increase in power consumption are suppressed. The present invention is a liquid crystal display device including a color filter substrate where color filters of at least four colors are arranged for respective pixels, wherein a color temperature of white light emitted from a display surface is less than 12000 K.
Claims12
A liquid crystal display device comprising:
- a color filter substrate where color filters of at least four colors are arranged for respective pixels,
- wherein a color temperature of white light emitted from a display surface is less than 12000 K.
A liquid crystal display device comprising:
- a color filter substrate where color filters of at least red, green, blue, and another color with higher brightness than the three colors including red, green, and blue are arranged for respective pixels,
- wherein chromaticity (x, y) of white light emitted from a display surface of the liquid crystal display device is within a range that fulfills the following (1) to (4).
- (1) When luminance of tricolor white light at a time when a color temperature is 12000 K is 100% in a tricolor liquid crystal display device comprising a color filter substrate where color filters of three colors including red, green, and blue are arranged, luminance of the white light is 100% or more.
- (2) When the luminance of the white light is 100%, luminance of red light emitted from the display surface of the liquid crystal display device is 12% or more.
- (3) When the luminance of the white light is 100%, luminance of green light emitted from the display surface of the liquid crystal display device is 30% or more.
- (4) When the luminance of the white light is 100%, luminance of blue light emitted from the display surface of the liquid crystal display device is 8% or more.
