Abstract: Displays such as liquid crystal displays may be provided with structures that minimize curtain mura. A display may have upper and lower polarizers. A color filter layer and a thin film transistor layer may be located between the upper and lower polarizers. A liquid crystal layer may be interposed between the color filter layer and the thin film transistor layer. A first optical film layer that includes a birefringent compensating layer may be located between the upper polarizer and the color filter layer. A second optical film layer that is devoid of birefringent compensating layers may be located between the thin film transistor layer and the lower polarizer. A grid of metal signal lines may be used to distribute signals to thin film transistors on the thin film transistor layer. A black mask may be interposed between the grid of signal lines and the thin film transistor layer.
