본 발명은 액정표시기의 표시내용을 양호하게 시인할 수 있도록 한 액정표시장치를 제공하는 것이다. 편광판(2c, 2d)을 전면측과 배면측에 설치한 액정표시기(2)를 수납하는 케이싱(6)과, 케이싱(6)의 전면 개구부를 덮는 합성수지제의 투시판(7)을 구비한 액정표시장치(1)에 있어서, 투시판(7)에는 케이싱(6)의 전면 개구부의 선단부 외측을 둘러싸도록 측벽(7a)을 설치하고, 그 측벽(7a)에는 액정표시기(2)를 시인하는 영역으로부터 떨어진 부분에 투시판(7)의 수지성형시에서의 게이트구(7c)를 설치하여 이루어짐으로써, 편광 안경 너머로 액정표시기(2)의 표시 내용을 보았다고 해도, 투시판(7)의 측벽(7a) 부분에 게이트구(7c)를 설치함으로써 게이트구(7c)로부터 떨어진 부분에서는 성형에 의한 굴절률 이방성을 갖지 않으므로 광이 통과하게 되어 액정표시기(2)의 표시내용을 양호하게 시인할 수 있다.

    Disclosed is a liquid crystal display device wherein display contents of a liquid crystal display can be excellently viewed. The liquid crystal display device (1) is provided with: a casing (6) which houses the liquid crystal display (2) provided with polarization plates (2c, 2d) on the front side and the rear side; and a see-through plate (7) which covers the front opening of the casing (6) and is composed of a synthetic resin. The see-through plate (7) is provided with a side wall (7a) such that the side wall surrounds the outer side of the end portion of the front opening of the casing (6), and on an area at a distance from a region where the liquid crystal display (2) is viewed, said area being on the side wall (7a), a gate port (7c) is provided when the see-through plate (7) is formed of the resin. Thus, even if the display contents of the liquid crystal display (2) are viewed through polarization glasses, light is transmitted since refractive-index anisotropy due to the formation is not generated in the area at a distance from the gate port (7c), by providing the gate port (7c) on the side wall (7a) area of the see-through plate (7), and the display contents of the liquid crystal display (2) can be excellently viewed.
