An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The display may include transistors with gate conductors, a first planarization layer formed over the gate conductors, one or more contacts formed in a first source-drain layer within the first planarization layer, a second planarization layer formed on the first planarization layer, one or more data lines formed in a second source-drain layer within the second planarization layer, a third planarization layer formed on the second planarization layer, and a data line shielding structure formed at least partly in a third source-drain layer within the third planarization layer. The data line shielding structure may be a routing line, a blanket layer, a mesh layer formed in one or more metal layers, and/or a data line covering another data line.
