An MVAMulti‐domain Vertical Alignment‐TFT LCD panel has been redesigned to improve optical performances and to reduce process step. The optical transmittance was improved by newly introduced protrusion wings to remove undesirable disclination lines caused by edge field effect of the pixel. Also, an aperture of the black matrix on the CF substrate was extended to include whole ITO pixel since the operating mode of the liquid crystal is Normally‐Black mode. The protrusions on the TFT substrate was replaced to patterned ITO slit. This results in the contrast ratio improvement, and simplifies the manufacturing process.
