Abstract: A liquid crystal display device includes a first substrate having a thin film transistor (TFT) in each pixel region, a first inorganic protective film on the first substrate including the TFT, color filters on the first inorganic protective film in each pixel region excluding the TFT, a common electrode on the color filters, a second protective film over the entire first inorganic protective film including the common electrode, a pixel electrode on the second inorganic protective film with the pixel electrode connected to a drain electrode of the TFT exposed by selective removal of the first and second inorganic protective films, the pixel electrode forming a fringe field with the common electrode such that the second inorganic protective film is interposed between the pixel electrode and the common electrode, and a column spacer on the second inorganic protective film with the column spacer covering the TFT.
