    摘要： A manufacturing method is provided for a liquid crystal display device that can avoid any possible inconvenience as a result of a difficulty in controlling the dropping amount of a liquid crystal. For executing the method, the liquid crystal display device has a pair of substrates disposed in an opposed manner including a liquid crystal display area with a diagonal length in a range from 1 inch to 5 inches, and a plurality of column spacers is formed in the liquid crystal display area of at least one of the substrates. The method includes the steps of: forming a sealant, with a width in a range from 0.4 mm to 1.0 mm, around the liquid crystal display area of the substrate formed with the column spacers; dropping a liquid crystal into the area enclosed by the sealant on the substrate such that a surface of the liquid crystal has a height lower than a height of the column spacers; disposing the other substrate to be opposed to the substrate formed with the column spacers, and pushing the resulting pair of substrates in a direction bringing the substrates closer to each other; and curing the sealant in a state that the column spacers each have the height in a percentage range from 108% to 113% as a result of dividing the height without the pushing by the height with the pushing.
