Thin film transistor substrate

A thin film transistor substrate, capable of being assembled to a filter substrate, for a semi-finished display crystal panel, the thin film transistor substrate comprising:

• a base substrate;
• a plurality of thin film transistors formed on the base substrate;
• a plurality of wiring assemblies formed on the base substrate and electrically connected to corresponding thin film transistors selectively;
• a plurality of metal sheets formed on the base substrate;
• a protection layer formed on the plurality of thin film transistors, the plurality of wiring assemblies, and the plurality of metal sheets;
• and
• a buffer module formed on the protection layer, wherein the buffer module is substantially positioned above a projection of a cutting line onto the base substrate, and a plurality of surplus materials of the filter substrate is removed along the cutting line.
