Abstract
The present invention provides a liquid crystal display panel of improving color washout, setting different alignment angles in the sub pixel areas of different colors (the included angle between the alignment direction of the liquid crystal molecules and the branch electrode of the pixel electrode). Then, the alignment angle of the red sub pixel area is the largest, and the alignment angle of the green sub pixel area is smaller, and the alignment angle of the blue sub pixel area is smallest. Thus, it is possible to respectively modulate the transmittance-voltage curves and the brightness-voltage curves of the lights of different colors to optimize the white dot chromaticity for satisfying the optical specification and compensate the losing transmittance of the blue light in the panel for improving the color washout problem.
