Theoretical and experimental characterizations reveal that the dark light leakage, which is induced by the curved corner at the cross of metal line, can be effectively weakened by decreasing the taper of metal line and increasing the length of barrier tail, finally contributing to 11.7% elevation of panel contrast ratio.
