| 摘要 |
A liquid crystal display device (10) of the present invention includes a backlight (3), a display liquid crystal panel (1) and a viewing angle control panel (2) for switching a viewing angle of the display liquid crystal panel (1) between a wide viewing angle mode and a narrow viewing angle mode. The viewing angle control panel (2) includes a control panel upper polarizing plate (22), a liquid crystal cell (21) and a control panel lower polarizing plate (23) stacked in this order, and phase difference plates (24, 25) are provided between the polarizing plates (22, 23) and the liquid crystal cell (21), respectively. The viewing angle control panel (2) is arranged such that Re1 in a white display portion in the wide viewing angle mode is nλ/2 (n is an integer of 1 or more), Re2 in a white display portion in the narrow viewing angle mode is nλ/2 (n is an integer of 1 or more), and Re3 in a black display portion in the narrow viewing angle mode is nλ (n is an integer of 1 or more).
