Liquid crystal display device

Abstract

A display device includes a display panel having a display region and a peripheral region, the display panel including a TFT substrate, a counter substrate fixed to the TFT substrate by seal material formed at the peripheral region, and liquid crystal interposed between the TFT substrate and the counter substrate. The TFT substrate includes an inorganic film and an organic film, with first column spacers being formed on the counter substrate. The organic film includes a first part which has an island-like shape formed at the peripheral region and a second part formed at the display region, and the seal material covers at least one of the first column spacers and the first part of the organic film, and is in contact with the inorganic film. The first part of the organic film is separated from the second part of the organic film of the organic film.
