Title: Wire bonding apparatus
Inventor: YAMANAKA KAZUYUKI
IPC: H01L21/60
Filed: 1987-09-02
Granted: 1990-10-18
Abstract: The device includes a camera for producing image signals corresponding to a field of view including an object having several target patterns on which wire bonding is to be performed. A displacement device serves for altering the field view of the camera by varying the relative positioning between the camera and the object.

Abstract: 본 발명은 수퍼 트위스틱 네마틱형(이하 STN 이라 한다)의 단순 매트릭스 타입의 액정표시장치에 관한 것으로, 표시의 착색 및 표시색의 시각의존성과 시야각이 개선된 액정표시장치를 제공하는 것을 목적으로 하는 것이다. 
     상기 목적을 달성하기 위해 본 발명의 액정표시장치는 대향하는 면 각각에 서로 교차하는 전극과; 이 전극을 덮어서 소정의 방향으로 배향처리가 실시된 배향막이 형성된 한쌍의 기판과 ; 이들 배향막의 사이에 존재하고, 한쪽의 기판에서 다른쪽의 기판으로 향하여 230°~250°의 범위에서 비틀림 배향된 액정재료와 ; 상기 한쌍의 기판의 외측에 이들 기판을 끼우도록 배치된 한쌍의 편광판과 ; 그리고 상기 한쌍의 편광판간에 배치되고, 서로 직교하는 연장방향 굴절율(n x ), 면내 직교방향 굴절율(n y ), 두께방향 굴절율(n x )이 n y n z n x 를 만족하는 이축성을 갖는 위상판을 적어도 1매 포함하는 복수의 위상판을 구비하여 이루어진 것을 특징으로 하는 것이다.
