Abstract

Abstract Translated from Japanese (57)【要約】 【構成】2枚の透明ガラス基板(11、12)の対向面 に帯状の表示用電極(31、32)をそれぞれ平行に両 基板の電極が互いに直交するように設け、その上に配向 膜(21、22)を設け、前記交差領域により表示ドッ ト領域(66)を構成し、両基板間の縁周囲に設けたシ ール材(52)により、両基板を貼り合わせ、かつ、両 基板間に液晶(50)とスペーサ(68)とを封止し、 両基板の外側に偏光板を配置し、最外列の電極(3 1′、32)の外側と表示ドット領域(66)内の電極 が存在しない部分を、電極が存在する部分とほぼ同一の 高さになるように配向膜(21、22)を用いて平坦化 した構成。 【効果】液晶表示素子の表示ドット領域全面の液晶層厚 を均一にすることができるので、コントラスト比が高 く、画面全面の表示状態が均一で表示むらのない高い表 示品質の液晶表示装置を提供することができる。 (57) [Summary] [Structure] Strip-shaped display electrodes (31, 32) are provided in parallel on the opposing surfaces of two transparent glass substrates (11, 12) so that the electrodes of both substrates are orthogonal to each other. An alignment film (21, 22) is provided thereon, a display dot area (66) is constituted by the intersection area, and both substrates are bonded together by a sealing material (52) provided around an edge between the two substrates. , A liquid crystal (50) and a spacer (68) are sealed between both substrates, Polarizing plates are placed on the outside of both substrates, and the electrodes (3 1 ', 32) and the display dot area (66) are flattened by using alignment films (21, 22) so that the portions where no electrodes are present have almost the same height as the portions where electrodes are present. The configuration. [Effect] Since the liquid crystal layer thickness of the entire display dot area of the liquid crystal display element can be made uniform, a liquid crystal display device having a high contrast ratio and a uniform display state on the entire screen and high display quality without display unevenness is provided. can do.
