摘要： An electronic device may have a display such as a liquid crystal display. The display may have a color filter layer and a thin-film transistor layer. An opaque masking layer may be formed on the color filter layer. An active portion of the display may contain an array of display pixels that are controlled by control signals that are provided over intersecting gate lines and data lines. In an inactive portion of the display, gate driver circuits may be used to generate gate line signals for the gate lines. Portions of the gate lines in the gate driver circuitry, power supply lines, and common electrode lines may be formed on the thin-film-transistor layer. These lines may be electromagnetically shielded using indium tin oxide shielding layers to prevent electric fields from inducing charge in the opaque masking layer and thereby causing color artifacts.
