Abstract:
A liquid crystal display device comprising:a driver substrate having a main surface on which a number of switching elements(active elements) corresponding to respective pixels are formed; a color filter substrate having a main surface on which a display area is formed by arranging color filters of more than one color corresponding to the respective pixels therein; and liquid crystals being sealed in a space defined by the main surface of the driver substrate, the main surface of the color filter substrate, and a sealing material sticking respective peripheries of the main surfaces to each other, wherein the color filters are covered with a transparent protective film, a common electrode is formed of a transparent conductive film above the transparent protective film in the display region, the sealing material is formed between an end of the common electrode and an end of the color filter substrate above the transparent protective film, columnar spacers are formed above the common electrode, between the end of the common electrode and the sealing material, and outside the sealing material over the transparent protective film, and an alignment film is formed at least partially on each surface of the columnar spacers, the common electrode, and the transparent protective film.
