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.

Abstract: Provided is a liquid crystal display device including: a first substrate; a second substrate opposite to the first substrate; and a liquid crystal layer between the first substrate and the second substrate, and includes pixels arranged in a matrix pattern. The pixels each include a reflective region in which display is provided in a reflective mode and a transmissive region in which display is provided in a transmissive mode. At least one of the pixels further includes a light blocking region inside the transmissive region. The second substrate includes a second substrate side insulating layer and a color filter layer sequentially toward the liquid crystal layer. The second substrate side insulating layer is placed in the reflective region and the light blocking region. A film thickness of the color filter layer in the transmissive region is greater than a film thickness of the color filter layer in the reflective region.
