1. A liquid crystal display device comprising:
a liquid crystal panel; and
a display panel that displays an image,
the liquid crystal panel including:
a first support substrate,
a second support substrate facing the first support substrate,
a polymer dispersed liquid crystal layer sealed between the first support substrate and the second support substrate,
first light-shielding portions extending parallel to one another,
second light-shielding portions extending parallel to one another in the same direction as the first light-shielding portions, and
an insulating layer located between the first light-shielding portions and the second light-shielding portions,
the second support substrate, the first light-shielding portions, the insulating layer, the second light-shielding portions, the polymer dispersed liquid crystal layer, and the first support substrate being located in the stated order from a back surface side toward a viewing surface side,
wherein in a plan view:
the first light-shielding portions are located at the same positions as the second light-shielding portions in a panel center,
the first light-shielding portions are shifted from the second light-shielding portions in a panel end, and
a width of each of the first light-shielding portions is equal to a width of each of the second light-shielding portions.
