摘要： A liquid crystal display device includes: a liquid crystal layer which contains a liquid crystal composition; a pair of substrates opposed to each other across the liquid crystal layer; alignment layers placed on liquid crystal layer sides of the pair of substrates, respectively; and polarization plates placed on opposite sides from the liquid crystal layer sides, respectively. The pair of substrates includes a thin-film transistor substrate including a thin-film transistor for controlling molecule alignment of the liquid crystal composition, and a color filter substrate including a color layer containing pixels of different colors. A blue pixel, which is one of the pixels of different colors, is larger in area than any of the pixels of other colors. A loss of light in a short-wavelength range is thus reduced.
