摘要：A color display device including a pair of substrates having a display portion and a peripheral portion. Gate signal lines and drain signal lines are formed on one substrate of the pair of substrates with a protective film being formed on the gate signal lines, the drain signal lines, and the one substrate including at least one of the peripheral portion and the display portion thereof. Color filters are formed on the other substrate and spacers are formed on the one substrate including the peripheral portion. At least two of the color filters are laminated in the peripheral portion, and a thickness of the protective film in the display portion is greater than a thickness of the protective film at a position of one of the spacers arranged in the peripheral portion.
