Patent ID: 8159432

Claim:
A liquid crystal display device, comprising: a plurality of pixels each connected to a signal line via a switching element; wherein each of the plurality of pixel includes a first sub pixel and a second sub pixel having voltage vs. luminance characteristics different from each other with respect to a signal voltage supplied from the signal line, a threshold signal voltage of the first sub pixel being lower than that of the second sub pixel; the plurality of pixels form color display pixels including a red pixel, a green pixel and a blue pixel; where the area ratio of the first sub pixel in each of the red pixel, the green pixel and the blue pixel is SR1, SG1 and SB1, and the ratio of a time period in which the first sub pixel of each of the red pixel, the green pixel and the blue pixel is lit up with respect to one vertical scanning period is TR1, TG1 and TB1, the relationship of (SR1×TR1)>(SG1×TG1)>(SB1×TB1) holds, and wherein SR1>SG1>SB1.
