Abstract
A thin-film liquid crystal display panel and a manufacturing method thereof in which an upper protection layer and a cell gap are formed by using a thin-film manufacturing technique usually used in the manufacture of semiconductors. The thickness of the cell gap is easily controlled, and the liquid crystal layer is uniformly formed. Therefore, a liquid crystal display panel with excellent liquid crystal driving capability is obtained.
