Abstract
(EN)
Provided is a liquid crystal display device that does not hinder a reduction in size and achieves excellent visibility. The liquid crystal display device is provided with: a display panel 31 having a display area including a first display area 32 and a second display area 33; a first control unit 21 for controlling a display in the first display area 32 by a duty driving scheme at a first duty ratio; and a second control unit 22 for controlling a display in the second display area 33 by the duty driving scheme at a second duty ratio higher than the first duty ratio.
