The present invention relates to a liquid crystal display device that is used in display portions of electronics devices and a manufacturing method thereof, and intends to provide a liquid crystal display device that can obtain excellent display quality and a manufacturing method thereof. The method of manufacturing a liquid crystal display device includes preparing a pair of substrates that have a structure P1 having a height Hp1 and a structure P2 having a height Hp2, the heights Hp1 and Hp2 satisfying a relationship of 0.3 (μm)≧Hp1−Hp2≦1.0 (μm); controlling a dropping amount V of liquid crystal so that a cell gap G1 that is determined by the dropping amount V of liquid crystal, the height Hp1 and the height Hp2 satisfy a relationship of Hp2
