PURPOSE:To provide the liquid crystal element which displays high-contrast images without generating after-images. CONSTITUTION:At least one of a pair of substrates 11a, 11b of the liquid crystal element having a pair of these substrates 11a, 11b and a liquid crystal 15 disposed between a pair of the substrates 11a and 11b have films 14a, 14b consisting of a compd. having the imide ring formed by the dehydration ring closure reaction of the amide acid obtd. from at least one kind of naphthalene tetracarboxylic acid and/or the deriv. thereof and at least one kind of diamine and/or the deriv. thereof. |
