<p><P>PROBLEM TO BE SOLVED: To obtain a transmissive liquid crystal display device that reduces luminous energy absorbed by not only a liquid crystal panel but also a color filter and can further reduce the power consumption. <P>SOLUTION: In the transmissive liquid crystal display device including a liquid crystal panel 15 and a backlight 17, the liquid crystal panel has pixels each divided into four sub-pixels of red (R), green (G), blue (B) and white (W). The backlight is a white backlight 17 by which luminance of emitted light is controllable. A first RGB input signal being an original input signal is subjected to saturation reduction processing by a saturation conversion part 11 and then is subjected toγcorrection by aγcorrection part 12. An output signal generation part 12 obtains transmissivity and a backlight value on the basis of the RGB input signal subjected toγcorrection by theγcorrection part 12. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
