Abstract
A liquid crystal display device includes: an active matrix substrate including a first electrode and a second electrode configured to generate a transverse electrical field; a counter substrate including a plurality of third electrodes disposed at predetermined intervals and having a stripe pattern; a liquid crystal layer located between the active matrix substrate and the counter substrate; and a control circuit. The liquid crystal display device can display an image in a first viewing angle mode and a second viewing angle mode having a viewing angle narrower than the first viewing angle mode by the control circuit switching an amplitude and a waveform of a voltage applied to the third electrodes. The control circuit applies a common voltage having a different value to the first electrode or the second electrode in each of the first viewing angle mode and the second viewing angle mode.
