Abstract:
An image display device includes a first liquid crystal panel, a second liquid crystal panel which faces a rear surface of the first liquid crystal panel, and a backlight which irradiates a rear surface of the second liquid crystal panel with light. The first liquid crystal panel includes a first front polarizer on a front surface of the first liquid crystal panel, a first rear polarizer on the rear surface of the first liquid crystal panel, and a first liquid crystal cell between the first front and rear polarizers. The second liquid crystal panel includes a second front polarizer on a front surface of the second liquid crystal panel, a second rear polarizer disposed on the rear surface of the second liquid crystal pane, and smaller than the first rear polarizer in top view, and a second liquid crystal cell between the second front and rear polarizers.
