AI Technical Summary
Technical Problem
Display panels using fan-out wiring in the display area (FIAA technology) are prone to display defects due to crosstalk of data signals caused by parasitic capacitance between intersecting fan-out lines and data lines.
Method used
A display panel design with a shielding portion between intersecting fan-out segments and data lines, which are insulated from each other, to reduce parasitic capacitance and crosstalk, utilizing a conductive layer structure with a shielding portion to mitigate display defects.
Benefits of technology
The shielding portion effectively reduces crosstalk and improves display quality by minimizing parasitic capacitance, enhancing the performance of display panels and devices.

Abstract
This application discloses a display panel and a display device. A first conductive layer includes a plurality of data lines located in the display area. A second conductive layer is located on one side of the first conductive layer and includes a plurality of first fan-out segments located in the display area and intersecting with the plurality of data lines. Each first fan-out segment is connected to one data line. A third conductive layer is installed between the first and second conductive layers and includes a shielding portion. The overlapping portion of one intersecting and insulating first fan-out segment and at least one data line overlaps with the shielding portion.
