Abstract
A liquid crystal display device according to the present invention includes an array substrate and a CF substrate. The CF substrate includes a lattice-shaped light shielding pattern between pixel electrodes and a columnar spacer at an intersection of the light shielding patterns. The array substrate and the CF substrate are disposed so as to face each other with a liquid crystal layer interposed therebetween. The intersection includes a portion in which signal lines intersect each other and a portion in which the signal lines do not intersect each other, whereby a step is provided on a surface of the array substrate. The columnar spacer includes a main spacer in the portion in which the signal lines intersect each other and a sub-spacer in the portion in which the signal lines do not intersect each other.
