An electronic device includes a substrate, multiple transversal signal lines, a first vertical signal line, a second vertical signal line, a shielding wire, and multiple pixel structures. The first vertical signal line is intersected with the transversal signal lines. The second vertical signal line is intersected with the transversal signal lines and connected to one of the transversal signal lines. An orthogonal projection of the shielding wire on the substrate is located between an orthogonal projection of the first vertical signal line and an orthogonal projection of the second vertical signal line on the substrate. One of the pixel structures is surrounded by a corresponding one of the transversal signal lines and the second vertical signal line and includes an active device.
