IPC: G02F1/1337
Filed: 1992-05-29
Abstract: PURPOSE:To prevent the local attraction of impurity ions to the film surfaces of oriented films and to suppress the seizure of a display by attracting the impurity ions in a liquid crystal to nearly the entire part of the film planes of the oriented films and preventing the suspension thereof. CONSTITUTION:This liquid crystal display element is constituted by having a pair of transparent substrates 1, 2 facing each other, forming respectively transparent electrodes 5, 6 for display on the inside surfaces of these transparent substrates 1, 2 and the oriented films 7, 8 covering these electrodes 5, 6 for display and sealing the liquid crystal 4 in the spacing where the transparent substrates 1, 2 face each other. The parts of the non-crystallized regions of the oriented films 7, 8 of such element are removed by etching, by which the surfaces of the oriented films 7, 8 are roughened. The surface areas of the film surfaces of the oriented films 7, 8 are increased by the surface roughening.
