Abstract
A liquid crystal display device is composed of an array substrate which includes a matrix array of pixel electrodes, a plurality of scanning liness formed along rows of the pixel electrodes, each for selecting the pixel electrodes of a corresponding row, a plurality of signal lines formed along columns of the pixel electrodes, for setting potentials of the pixel electrodes of a selected row, and an alignment film formed to cover the pixel electrodes, the scanning lines and the signal lines, a counter substrate which includes a counter electrode facing the matrix array of pixel electrodes, and an alignment film formed to cover the counter electrode, and a liquid crystal layer which is held between the array substrate and the counter substrate and has liquid crystal molecules aligned by the alignment films of the array and counter substrates. In the liquid crystal display device, the scanning line is formed to have a cutout at an intersection of the scanning and signal lines located on a side corresponding to pretilt-base ends of the liquid crystal molecules aligned by the alignment film of the array substrate, and the cutout is determined to reduce an electric field produced in the liquid crystal layer between the scanning line and the pixel electrode.
