We report on novel pixel architecture for improving the transmittance and reducing the gamma distortion to minimize the color shift in an 8K QUHD LCD panel with the hG‐2D technology. In our LCD panel, each pixel has a unique electrode structure which is mixed with conventional micro‐slits and reversed those. It is named “multi‐domain reversed‐slit VA mode (MRS‐VA)”. This MRSVA‐LCD has the excellent transmittance by matching the LC distortions on the vertical electrode and two data lines which is asymmetrically positioned. Besides, by shielding the LC distortion line at the oblique viewing angle, the gamma distortion can be effectively suppressed. Through our pixel structure, superior performances to conventional LCD could be clearly proved (GDI value: 0.345 and panel transmittance (T): 3.7%). Additionally, by demonstrations of overcoming the crosstalk and bruising defects, we demonstrated that MRSVA‐LCD could be applied to the commercial 8K panels manufactured by the mass production.
