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.

Liquid crystal display panel and liquid crystal module

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.
