Abstract

To provide a liquid crystal display device and the like, which can improve the contrast ratio. The liquid crystal display device includes a liquid crystal display unit and an image processing unit which supplies video signals inputted from a video source section to the liquid crystal display unit. The liquid crystal display unit is formed by stacking a single first liquid crystal display element and a single or a plurality of second liquid crystal display element(s). For each pixel unit of the second liquid crystal display element, the image processing unit generates, by having each dot of the video signal as a reference point, a drive signal for displaying an image according to processing for extracting a maximum value of relative gradations or relative transmittances among a region of a pixel unit (dot) group including the reference pixel units and the pixel units (dots) neighboring to the reference pixel units.
