Abstract
Disclosed are a liquid crystal display panel with adjustable viewing angle and a method for adjusting the viewing angle. A pixel unit located in a display area of the liquid crystal display panel includes a main pixel area and a sub pixel area. The main pixel area is horizontally aligned. The sub pixel area is vertically aligned. In the sub pixel area, an upper substrate electrode is arranged beneath the upper substrate and a lower substrate electrode is arranged on the lower substrate. In the sub pixel area, the upper substrate electrode and the lower substrate electrode both have a double layer electrode structure, and bias voltages, under an action of which liquid crystal molecules in the sub pixel area are aligned horizontally, vertically and obliquely, are exerted on the upper substrate electrode and the lower substrate electrode, thereby realizing switching between a narrow viewing angle mode and a wide viewing angle mode.
