Abstract

The invention provides a TFT array substrate. The TFT array substrate comprises a substrate layer and a metal layer arranged on the substrate layer. The metal layer comprises a first metal layer and asecond metal layer arranged on the first metal layer, the first metal layer comprises a main body part and a tail part, the main body part of the first metal layer upwards corresponds to the second metal layer, and the tail part of the first metal layer is the part, extending out of the second metal layer from the side end part of the main body part, of the first metal layer. According to the TFTarray substrate provided by the invention, a novel metal layer morphology characteristic is adopted, so that the light leakage condition of the array substrate in a dark state is effectively improved, and the contrast ratio of a product is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, a TFT array substrate and a display panel thereof. Background technique [0002] It is known that, with the continuous development of flat display technology, the industry continues to introduce better display effects and lighter flat-panel displays, such as liquid crystal displays, OLED displays, and the like. Although these flat-panel displays have different specific structures due to different light-emitting principles, they all have a common component, that is, a TFT array substrate. [0003] The TFT array substrate, as an important part of the display driving part, is a key component for realizing the normal display function of the display. On the TFT array substrate, a metal layer is provided to form electronic components of a functional circuit and transmit data signals. [0004] Furthermore, with the advancement of information technology, the flat panel display i...
