Abstract
A liquid crystal composition for liquid crystal lens and a stereoscopic (3D) display containing the same are provided. The liquid crystal composition includes a main liquid crystal (chemical formula I), a first optical modifier (R811 or S811), a second optical modifier (CB15), and a dielectric constant modifier (chemical formula IV). The 3D display utilizes a horizontal electric field to make the above liquid crystal composition form crystal lens.
