Abstract: A display device includes a primary display area which comprises a first display area and a second display area which is unique from the first display area, a control unit configured to display an image in the primary display area, an image signal generating unit configured to generate display data based on externally input image data for a single image. The image signal generating unit comprises a memory which stores display-position information indicating a display location of a first image displayed in the primary display area. The display data comprises first and second display data to be displayed in the first display area and the second display area, respectively. The first display data is generated based on the externally input single image data and the display-position information. The control unit is configured to cause a first image to be displayed in the first display area based on the first display data.

Abstract: A method of setting a common electrode voltage of a liquid crystal display panel in a liquid crystal module is provided. The liquid crystal module includes the liquid crystal display panel including an alignment film, and a backlight disposed behind the liquid crystal display panel. The method of setting a common electrode voltage of a liquid crystal display panel includes: eliminating an electric charge of the alignment film by turning on the backlight without driving the liquid crystal display panel to emit light of the backlight onto the liquid crystal display panel; and setting the common electrode voltage of the liquid crystal display panel by adjusting the common electrode voltage, after the eliminating of the electric charge.

Abstract: A liquid crystal display panel to be used in a vertical orientation includes: a first substrate; a second substrate located opposite to the first substrate; and a liquid crystal layer disposed between the first substrate and the second substrate. When a position of a top end of the liquid crystal layer is defined as a first position and a position of a bottom end of the liquid crystal layer is defined as a second position when the liquid crystal display panel is placed in the vertical orientation, a distance between the first substrate and the second substrate when the liquid crystal panel is in a horizontal orientation gradually decreases from the first position to the second position.
