A liquid crystal display device includes a liquid crystal display panel, a first polarizer between the liquid crystal display panel and a back light behind the liquid crystal display panel, the first polarizer including a first polarization film having a first transmission axis and a first phase-difference film having a first polarization axis, a second polarizer in front of the liquid crystal display panel, the second polarizer including a second polarization film having a second transmission axis intersecting the first transmission axis, a second phase-difference film having a second polarization axis intersecting the first polarization axis, and a third phase-difference film having a third polarization axis, and a substrate structure above the liquid crystal display panel and the second polarizer, the substrate structure includes a third polarizer in the substrate structure, the third polarizer including a fourth phase-difference film having a fourth polarization axis intersecting the third polarization axis.
