Problems solved by technology

[0003] The inventors of this application have found in long-term research and development that in the existing organic light-emitting display panels, because the second layer of metal used for VDD / Sense wiring, one of the electrode plates of the storage capacitor is also used for the second layer of metal. Due to the limitation of the layout space and the short distance, the VDD / Sense traces are easily short-circuited with the electrode plates of the storage capacitors, resulting in abnormal bright spots on the display panel.

Abstract

Disclosed are a TFT substrate, a display panel and a display apparatus. The TFT substrate at least comprises a first thin-film transistor and a storage capacitor arranged on the substrate. The storage capacitor comprises: a first electrode layer, a second electrode layer and a third electrode layer, wherein the first electrode layer, the second electrode layer and the third electrode layer are all arranged on a different layer from a source and drain electrode layer of the first thin-film transistor, and the second electrode layer is arranged between the first electrode layer and the third electrode layer. In this way, abnormal bright spots of a display panel can be reduced, improving the display effect.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a TFT substrate, a display panel and a display device. Background technique [0002] With the development of the information society, various forms of display devices for displaying images are required. In recent years, devices such as liquid crystal displays, plasma display panels, and organic light-emitting display devices have been widely used. The display device includes a display panel, and the display panel includes thin film transistors and storage capacitors in each pixel area, wherein the storage capacitors are used to increase the charge storage capacity of the pixels, and maintain the pixel potential before the next scanning period arrives. [0003] The inventors of this application have found in long-term research and development that in the existing organic light-emitting display panels, because the second layer of metal used for VDD / Sense wiring, o...
