Abstract

A pixel unit of an FFS type TFT-LCD array substrate comprises a slit electrode. The slit electrode comprises at least one slit unit, a direction from one side of the slit unit to the opposite side of the slit unit is defined as a first direction, the slit unit comprises a plurality of slits, extending in a same direction and arranged along the first direction, and electrode parts between two adjacent slits. The sum of the width of each electrode part and the width of a slit adjacent to the electrode part at a side in the first direction increases gradually along the first direction.
