Abstract
A liquid crystal display may have a thin-film transistor layer with an array of pixel electrode structures for applying electric fields to a liquid crystal layer. The liquid crystal display may also have a color filter layer with an array of color filter elements. The color filter elements may allow the display to display color images. The color filter layer may be interposed between the thin-film transistor layer and a backlight. The liquid crystal layer may be sandwiched between the thin-film transistor layer and the color filter layer. The color filter layer may have a transparent substrate on which the color filter elements are formed. Black masking structures may be formed on a transparent overcoat layer that covers the color filter elements. Black column spacers may be formed from the same layer of material that forms the black masking structures.
