The first substrate is provided with a first electrode and a first alignment film. The second substrate is provided with a second electrode, a third electrode and a second alignment film. The liquid crystal molecules adjacent to the first alignment film are tilted at a first pretilt angle. The liquid crystal molecules adjacent to the second alignment film are tilted at a second pretilt angle. The second pretilt angle is in the range of 30° to 50°, and the first pretilt angle is in the range of 0° to 5°. When no bias voltage is applied to the first electrode, the LCD is displayed with a narrow viewing angle; and when a bias voltage is applied to the first electrode, the LCD is displayed with a wide viewing angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display with switchable viewing angle and method of viewing angle control","description":"An LCD with switchable viewing angle includes a first substrate, second substrate, and a liquid crystal layer.
