Abstract
An active-matrix liquid crystal display device having a pair of substrates at least one of which is transparent, a liquid crystal layer disposed between the pair of substrates, a group of electrodes for applying to the liquid crystal layer an electric field substantially parallel to the substrate plane and a plural number of active elements being formed on one of the pair of substrates and an alignment layer disposed between the liquid crystal layer and at least one of the pair of substrates. The alignment layer is a photo-reactive material layer, and the photo-reactive material layer is a photo-reactive alignment layer which has been subjected to linearly polarized light irradiation to selectively derive a photochemical reaction and a tilt angle of liquid crystal molecules on the alignment layer surface of the substrate is 3° or less.
