Active-matrix addressing liquid-crystal display device and method of fabricating same |
摘要 |
An active-matrix addressing LCD device that suppresses effectively the off leakage current induced by the charge-up of the spacers placed over the TFTs. The device comprises (a) a first substrate having switching elements; (b) a second substrate coupled with the first substrate in such a way as to form a gap with spacers between the first and second substrates; the spacers being distributed in the gap; (c) a liquid crystal confined in the gap; and (d) protrusions formed in overlapping areas with the switching elements; each of the protrusions being protruded in a direction that narrows the gap. The spacers distributed in the gap are likely to be shifted away from the overlapping areas due to the protrusions.
