<p>The purpose of the present invention is to provide an optical device having a resolution, reflected-image diffusibility, and antiglare properties suitable for in-vehicle use. The present invention is an optical device comprising a display device, and a transparent substrate arranged on the display surface side of the display device. If the transparent substrate is evaluated by using three index values, i.e., a resolution index value T, a reflected-image diffusibility index value R, and a glare index value S, the transparent substrate satisfies the following: resolution index value T≤0.2; reflected-image diffusibility index value R≥0.2; and glare index value S≤60. The present invention can be used for an optical device in which a transparent substrate is provided on the display surface side of one of various types of display devices, such as LCD devices, OLED devices, and PDP devices.</p> |
