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.
摘要翻译：提供一种用于液晶显示装置的制造方法，其可以避免由于难以控制液晶的滴落量而导致的任何可能的不便。为了执行该方法，液晶显示装置具有以相对的方式设置的一对基板，其包括对角线长度在1英寸至5英寸的范围内的液晶显示区域，并且多个列间隔件形成在至少一个基板的液晶显示区域。该方法包括以下步骤：在形成有柱间隔物的基板的液晶显示区域周围形成宽度为0.4mm至1.0mm的密封剂; 将液晶滴入由基板上的密封剂包围的区域中，使得液晶的表面的高度低于柱状间隔物的高度; 将另一基板设置成与形成有柱间隔物的基板相对，并且使所得到的一对基板沿使基板更靠近的方向推压; 并且在所述柱状隔片各自具有从108％至113％的百分比范围内的高度的状态下固化所述密封剂，这是由于在不推动所述高度的情况下将所述高度除以所述高度。
