Abstract

A liquid crystal display device of the present invention comprises a first substrate and a second substrate, each of which has a glass substrate, an electrode portion formed on the glass substrate, and an orientation film formed on the electrode portion. The first substrate and the second substrate are opposed to each other and have a liquid crystal layer encapsuled therebetween. The electrode portion includes: a display-portion electrode group formed within a display-screen region; an extraction electrode group leading the display-portion electrode group outward from at least one side of the display-screen region; and an external electrode group formed outside the display-screen region. The periphery of the external electrode group, positioned on an external area of a side on which the extraction electrode group in the display-screen region is not formed, is covered with the orientation film.
