    Abstract: A display may have a thin-film transistor layer and color filter layer. The display may have an active area and an inactive border area. Light blocking structures in the inactive area may prevent stray backlight from a backlight light guide plate from leaking out of the display. The thin-film transistor layer may have a clear substrate, a patterned black masking layer on the clear substrate, a clear planarization layer on the black masking layer, and a layer of thin- film transistor circuitry on the clear planarization layer. The black masking layer may be formed from black photoimageable polyimide. The clear planarization layer may be formed from spin-on glass. The light blocking structures may include a first layer formed from a portion of the black masking layer and a second layer such as a layer of black tape on the underside of the color filter layer.

    Abstract: An electronic device (10) may be provided with a display (14) mounted in a housing (12). The display may include a color filter substrate (56), a liquid crystal layer (56), and a thin-film transistor substrate (58). The color filter substrate may form the outermost layer of the display. The color filter substrate (56) has a substrate (104) having opposing inner and outer surfaces (118, 116). A layer of patterned metal on the inner surface may form metal alignment marks (120). The metal alignment marks may include alignment marks (120R, 120G, 120B) for color filter elements (106R, 106G, 106B), alignment marks (120BM) for a black matrix layer (108) that is formed on top of the color filter elements, and post spacer alignment marks (120PS). The layer of patterned metal may also form structures such as logo structures (100) that are visible on the outer surface (106) in an inactive border region (IA) of the display (14).
