Abstract
An active matrix type liquid crystal display device including first and second substrates, a liquid crystal composition layer provided between the first and second substrates, a plurality of drain lines and gate lines formed on the first substrate and crossing each other in a matrix form, a plurality of reference lines formed on the first substrate, and a plurality of pixels formed by adjoining the drain lines and the gate lines. At least one pixel electrode is formed in each pixel with the pixel electrode having first and second layers. An area of the first layer is smaller than that of the second layer, and a ratio of an overlapped area between the first layer and one of the reference lines to an area of the first layer is greater than that between the second layer and the one of reference lines to an area of the second layer.
