| Abstract | The purpose of the present invention is to provide a video display device that makes it possible to readily and precisely identify the polarization axis direction of a reflective polarizing plate andto adjust the polarizing reflection axis direction with high precision, as well as a wire-grid polarizing plate, etc. that make it possible to readily check the polarization axis direction. A head-updisplay device (1) according to the present invention is a video display device provided with: a video display (14) that emits video light, which is polarized light; a reflective polarizing plate (15)having a reflecting face (28) that reflects the video light; and a projection plate (11) on which the video light reflected by the reflective polarizing plate is projected, and characterized in thatthe reflective polarizing plate enables observation of a bright line (B) serving as an indication of the polarization axis direction of the reflecting face.
本发明的目的在于，提供一种能够简单且高精度地识别反射型偏振片的偏振轴方向并且高精度地对偏振反射轴方向进行调节的影像显示装置、以及能够简单地调查 |
