Abstract
A display may have a layer of liquid crystal material between a color filter layer and a thin-film transistor layer. Column spacer structures may be formed between the color filter layer and the thin-film transistor layer to maintain a desired separation between the color filter and thin-film transistor layers. Column spacers may be deposited in column spacer regions of the color filter layer. The color filter layer may include rows of red, green, and blue color filter elements. Blue color filter material that forms blue color filter elements in the color filter layer may also be used to form a planar surface over red and green color filter elements in the column spacer regions. Using the blue color filter material to planarize the surface on which column spacers are formed ensures that the column spacers provide sufficient support for the display without requiring an additional planarization layer.
