Abstract
A display unit capable of inhibiting moisture and gas from penetrating into a liquid crystal layer and an alignment layer also after formation of a display electrode and suppressing decomposition of a material forming the display electrode is obtained. In this display unit, an impurity-introduced layer containing an impurity element having high electronegativity is formed on the surface of an insulator film and the surface of the display electrode after formation of the display electrode. Thus, the insulator film and the display electrode are improved in effects of preventing transmission of moisture and gas also after formation of the display electrode. The impurity-introduced layer formed on the surface of the display electrode stabilizes the surface of an ITO film forming the display electrode, thereby suppressing decomposition of the ITO film.
