Problems solved by technology

Remaining grid lines will lead to grid line-transparent electrode short circuit problems, and residual transparent electrodes will cause defective pixels, which not only becomes a very serious quality problem, but also greatly affects the production of array substrates, resulting in a decrease in yield

Abstract

The invention relates to an FFS-type TFT-LCD array base plate structure and a manufacturing method thereof. The array base plate structure includes a glass base plate, a grid electrode formed on the glass base plate, a grid line, a common electrode line and a transparent electrode, a grid insulating layer formed on the glass base plate, an active layer and a source-drain electrode layer sequentially formed on the glass base plate and arranged above the grid electrode, a passivation layer formed on the glass base plate, a via hole formed on the passivation layer, a blocking channel formed on the passivation layer and used for blocking off the grid line and the common electrode line, and a pixel electrode formed on the passivation layer and connected with the drain electrode in the source-drain electrode layer through the via hole. Through adding the blocking channel into the arranged base plate, the invention can efficiently repair the badness caused by the grid line residual and the common electrode residual. The invention introduces the repair concept into the process of designing a mask plate, and has good effect on repairing the badness caused by the grid line residual and the common electrode residual, etc.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to an FFS type TFT-LCD array substrate structure and a manufacturing method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. Fringe Field Switching (FFS for short) generates a fringe electric field through the electrodes between pixels in the same plane, so that the aligned liquid crystal molecules between the electrodes and directly above the electrodes can be rotated in the direction of the plane (parallel to the substrate). The light transmission efficiency of the liquid crystal layer is improved while the viewing angle is large. [0003] The prior art FFS type TFT-LCD array substrate structure includes a glass substrate, a ...
