摘要:
A liquid crystal display device, comprising: a pair of substrates at least one of which is transparent; a liquid crystal layer arranged between the pair of substrates; a group of electrodes for applying an electric field to the liquid crystal layer, as formed on at least one substrate of the pair of substrates; a plurality of active elements connected to the group of electrodes; and an orientation film arranged on the pair of substrates, wherein at least one orientation film contains a polyimide having a specific chemical structure of any of an anionic organic acid except organic acids in the narrow sense, or an acid ester group of an anionic organic acid except organic acids in the narrow sense.
