<p>PURPOSE:To prevent the occurrence of a printing phenomenon and an after-image phenomenon by setting the film thickness of a liquid crystal orienting film to 200-3000Angstrom . CONSTITUTION:This active matrix liquid crystal display element consists of a base plate 1 provided with a transparent electrode 4, an orienting film 6, and a base plate 2 provided with a black matrix 9, a transparent electrode 5, an active element such as a transistor (TR), an electric conductor 3, and an orienting film 7, and a liquid crystal layer 8. The orienting films which orient liquid crystal molecules on the surfaces of the substrates at a 3-4 deg. tilt angle, i.e. orienting films which are 200-3000Angstrom thickness are provided by sintering a polyimide precursor whose carbon number is 12 for a cyclobutabutadiene ring and a terminal alkyl group. Consequently there is no discrimination due to an electric field from the electric conductor and neither the printing phenomenon nor the after-image phenomenon is generated.</p> |
