ABSTRACT:
A liquid crystal display device comprises a first sub-pixel electrode and a second sub-pixel electrode together forming a pixel cell, a dual thin film transistor having two electrodes electrically connected to the first and second sub-pixel electrodes respectively, and a connecting layer formed between the first and second sub-pixel electrodes. When one of the first and second sub-pixel electrodes is defective, the electrical path between the defective one and the dual thin film transistor is cut; then, the first and second sub-pixel electrodes are electrically connected together through the connecting layer whereby repairing the defective pixel cell.
