Abstract
A liquid crystal display (LCD) viewing angle control method, an LCD panel and an LCD are disclosed. The method is applied in the LCD panel comprising an array substrate and a color filter substrate which are arranged opposite to each other. The method comprises the following steps of: arranging a first planar transparent electrode (13) in the color filter substrate of the LCD panel and a second strip transparent electrode (17) in the array substrate of the LCD panel, and forming a fringe electric field between the array substrate and the color filter substrate through the first planar transparent electrode (13) and the second strip transparent electrode (17); and controlling the display viewing angle of the LCD panel by controlling the formed fringe electric field. Moreover, the method can achieve a simple production process of the LCD panel.
