A normally black liquid crystal display device includes a liquid crystal layer in which liquid crystal molecules are arranged vertically when no voltage is applied, and arranged horizontally by applying a voltage. In each of pixel regions in alignment films which are segmented in a grid by source lines and gate lines, is divided into two along a direction parallel to the source lines. The first alignment film includes a first region and a second region. The second alignment film includes a third region facing the first region and a fourth region facing the second region. In an adjacent pair of the pixel regions, pairs of the regions are adjacent to each other with corresponding one of the source lines interposed therebetween.
