The alignment film 18 covering the pixel electrode 15 and the alignment film 24 covering the counter electrode 23 are selected depending on optical design of the liquid crystal device 100. For example, the alignment films 18 and 24 include an organic alignment film obtained by film forming an organic material such as polyimide into a film, and rubbing the surface thereof to apply a process to cause liquid crystal molecules having positive dielectric anisotropy to be substantially horizontally aligned, and also includes an inorganic alignment film obtained by film forming an inorganic material such as SiOx (silicon oxide) into a film using vapor phase growth method to cause liquid crystal molecules having negative dielectric anisotropy to be substantially vertically aligned.
Such a liquid crystal device 100 is of a transmissive-type, and employs an optical design of a normally white mode in which the transmittance of the pixels P is maximum in a state where voltage is not applied, or of a normally black mode in which the transmittance of the pixels P is minimum in a state where voltage is not applied. A polarizing element is disposed on each of the light incidence side and the light exit side of the liquid crystal panel 110 including the element substrate 10 and the counter substrate 20 in accordance with the optical design to be used.
In the present exemplary embodiment, description will be made of an example in which an inorganic alignment film described as the alignment film 18 and 24, and liquid crystal having negative dielectric anisotropy are used, and an optical design of a normally black mode is employed.
