Problems solved by technology

[0003] In order to increase the screen-to-body ratio, the current common practice is to reduce the size of the bezel area, but the signal traces in the bezel area will be too dense, and capacitive coupling between signal traces will easily occur, resulting in various mura on the display device.

Abstract

The invention discloses a display panel and a display device, comprising: a device setting area, a first non-display area and a display area, the first non-display area is set around the device setting area, and the display area is set around the first non-display area; the display area It includes a plurality of data lines, a common electrode layer, and a plurality of thin film transistors arranged on the base substrate; wherein, the plurality of data lines include a plurality of first data lines and a plurality of second data lines; the first data lines include a conventional part and the connection part, the conventional part is located in the display area, the connection part is located in the first non-display area, and is set around the device setting area; the thin film transistor includes a gate, a semiconductor part, a source and a drain, the source, the drain, the second The data line and the regular part are arranged in the same layer and the same material; the first non-display area includes at least one shielding layer, and the at least one shielding layer and the connecting part are arranged in different layers. Compared with the prior art, it is beneficial to improve the mura caused by the coupling of the display panel and increase the screen-to-body ratio of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Display devices such as mobile phones and tablet computers need to reserve installation areas for devices such as cameras and photoelectric sensors. These installation areas are usually set at the top of the display area of ​​the display device, and the signal lines that originally passed through the installation area need to bypass the installation area. , so that the frame area between the installation area and the display area for signal routing can only be used as a non-display area, reducing the screen ratio of the display device. [0003] In order to increase the screen-to-body ratio, the current common practice is to reduce the size of the bezel area, but the signal traces in the bezel area will be too dense, and capacitive coupling between signal traces will easily occur, resulting in va...
