Abstract

The invention discloses a thin film transistor-liquid crystal display (TFT-LCD) array substrate and a double-tuned mask board for manufacturing the array substrate. The array substrate comprises a source electrode, a drain electrode and a thin film transistor (TFT) channel, wherein lug bosses are respectively arranged on two sides of the TFT channel. By forming the lug bosses on the two sides of the TFT channel, higher excessive corrosion is caused immediately, parameters of the TFT channel can be guaranteed, the actual width of the TFT channel is increased, the delay of signal transmission of the TFT channel is reduced, the response time of a liquid crystal display (LCD) is improved, and the performance of the LCD is improved.

Description

technical field [0001] The invention relates to a TFT-LCD, in particular to a TFT-LCD array substrate capable of improving the display performance of the TFT-LCD and a double tone mask for manufacturing the array substrate. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) is a main flat panel display (Flat Panel Display, FPD for short). [0003] According to the direction of the electric field driving the liquid crystal, the TFT-LCD is divided into a vertical electric field type and a horizontal electric field type. Among them, the vertical electric field TFT-LCD needs to form pixel electrodes on the array substrate and the common electrode on the color filter substrate; however, the horizontal electric field TFT-LCD needs to form the pixel electrodes and common electrodes on the array substrate at the same time. Therefore, when manufacturing the array substrate of the horizontal electric field type TFT-LCD, it is necessary to ad...
