Abstract
An ECB-type vertically aligned liquid crystal device includes liquid crystal molecules each having a negative dielectric anisotropy and polyimide films for homogeneous alignment. In a process for manufacturing the liquid crystal device, the liquid crystal molecules are vertically oriented by exposing the liquid crystal molecules to light from either or both sides of substrates of the liquid crystal device. In addition, an aligner used for exposure is equipped with a filter so as to cut light having wavelengths of 400 nm or less and 600 nm or more, so that light having a wavelength of 400 to 600 nm can be utilized In this liquid crystal device, the response time becomes faster when a voltage is applied between electrodes.
