Abstract
In an active matrix type liquid crystal display apparatus, respective ones of the electrodes on a substrate are provided so that an electric field substantially parallel to the substrate can be supplied to a liquid crystal layer. Polarizers for changing the optical characteristics based on the alignment of the liquid crystal layer are provided, as well as a shielding layer formed in parallel to the image signal electrodes on the substrate. The specific resistivity of the shielding layer is less than 10.sup.8 .OMEGA..multidot.cm.
