1. A liquid crystal display device comprising a direct-view liquid crystal panel having a Bayer array of green first and third pixels, and a blue second pixel and a red fourth pixel, the first pixel being connected to a first scanning signal line and a first data signal line through a first transistor, the second pixel being connected to the first scanning signal line and the first data signal line through a second transistor;
wherein the first pixel forms an auxiliary capacitor with a first auxiliary capacitor line, and the second pixel forms an auxiliary capacitor with a second auxiliary capacitor line;
a luminance of the first pixel is higher than a luminance of the second pixel in a first field period, the luminance of the second pixel is higher than the luminance of the first pixel in a second field period;
wherein the first field period and the second field period are alternately displayed repeatedly;
wherein in the first field period, a luminance of the second pixel is not more than 1/10 of the luminance of the first pixel; and
wherein in the second field period, a luminance of the first pixel is not more than 1/10 of the luminance of the second pixel.
