    • The invention provides a projection display that achieves continuous light amount control with ease and without causing unevenness of illumination of light applied to a light valve responsive to a video signal, thereby allowing constant image display with satisfactory contrast. The projection display of the invention includes a light valve (2); a light source (3a) generating light applied to the light valve (2); an integrator lens (4) provided on an optical path between the light source (3a) and the light valve (2) and making uniform the illumination distribution of light applied from the light source (3a) to the light valve (2); and a light amount control system (9) provided on the optical path and including a turning mechanism (9a) which turns like a set of double doors in order to adjust the amount of light applied from the light source (3a) to the light valve (2). The turning mechanism (9a) is bent into a V shape in a direction to reduce the amount of light (to block the light).
    • 本发明提供了一种能够容易地实现持续的光量控制并且不会根据视频信号而引起施加到光阀的光的照明不均匀的投影显示器,从而允许具有令人满意的对比度的恒定的图像显示。 本发明的投影显示器包括一个光阀(2); 产生施加到所述光阀(2)的光的光源(3a); 设置在光源(3a)和光阀(2)之间的光路上并使从光源(3a)施加到光阀(2)的光的照明分布均匀的积分透镜(4); 以及光量控制系统(9),其设置在所述光路上并且包括转动机构(9a),所述转动机构(9a)像一组双门一样转动,以便将从所述光源(3a)施加的光量调节到所述光阀 (2)。 转动机构(9a)沿着减少光量(阻挡光)的方向弯曲成V字状。
