Abstract:
1. A liquid crystal display device comprising: a first substrate having a plurality of pixel regions defined by a plurality of gate lines and a plurality of data lines crossing each other; a thin film transistor formed in each pixel region; a first inorganic protective film on the first substrate including the thin film transistor; color filters formed on the first inorganic protective film in each pixel region excluding the thin film transistor; a common electrode formed on the color filters; a second protective film formed over the entire surface of the first inorganic protective film including the common electrode; a pixel electrode formed on the second inorganic protective film, such that the pixel electrode is connected to a drain electrode through a drain contact hole exposing the drain electrode; and a column spacer formed on the second inorganic protective film such that the column spacer covers the thin film transistor, wherein the first inorganic protective film directly contacts the second inorganic protective film at a portion surrounding the drain contact hole.
