Abstract
The invention relates to a substrate for a liquid crystal display device used as a display part of an electronic equipment and a liquid crystal display device including the same, and has an object to provide a substrate for a liquid crystal display device in which high manufacturing yield and excellent display quality can be obtained, and a liquid crystal display device including the same. The substrate for the liquid crystal display device includes a base substrate for holding a liquid crystal in cooperation with an opposite substrate arranged to be opposite thereto, and a pillar spacer provided to maintain a cell gap between the base substrate and the opposite substrate, wherein the pillar spacer includes a first layer formed on the base substrate to linearly extend in a first direction and to have an almost constant width W in a second direction orthogonal to the first direction, and a second layer which is patterned to partially overlap with the first layer at an overlap accuracy X and in which a width in the first direction is almost constant and a length L1 in the second direction satisfies a relation of L1.gtoreq.W+2X.
