摘要： The invention relates to a gate driving device for Thin Film Transistor liquid crystal display comprising: a plurality of shift registers directly deposited on an array substrate, said shift registers being composed of effect transistors and a capacitor, obtaining a gate driving signal voltage by controlling an input signal. Said shift register can be realized by 5-layer mask process or 4-layer mask process, by arranging the field effect transistors on the margin part outside the active region on the substrate or at the edge of the substrate, and then directly depositing them on an array substrate. The invention obtains a gate driving signal voltage by the shift registers directly deposited on the substrate, thus overcoming the shortage of the need of driving chips and film layers in the prior art, substantially reducing the production cost for LCD.
