Title: LIQUID CRYSTAL DISPLAY PANEL FOR IMPROVING COLOUR CAST
Abstract:
A liquid crystal display panel for improving a colour cast. By arranging different alignment angles (including angles between an alignment direction of a liquid crystal molecule and a branch electrode (12) of a pixel electrode) in sub-pixel regions with different colours, an alignment angle of a red sub-pixel region (R) is the largest, an alignment angle of a green sub-pixel region (G) is smaller, and an alignment angle of a blue sub-pixel region (B) is the smallest, so that transmittance-voltage curves and brightness-voltage curves of light of different colours can be modulated respectively, the chroma of a white dot is optimized to satisfy optical specifications, the lost transmittance of blue light in the panel can also be compensated, and the colour cast problem of the panel is improved.
