  • Publication number: 20180231837
    Abstract: Provided is a display device serving as a see-through display which is capable of ensuring the clarity of a displayed image while maintaining high transparency and is less likely to be limited in terms of the location of installation. A dot-printed light-emitting area of a light guiding plate (60) emits, as backlight, light whose intensity is so high that the intensity of ambient light can be negligible, and therefore, the observer on the front side of a liquid crystal display device (10) is able to see a clear image displayed in an image display area (75) of a liquid crystal panel (20). Moreover, ambient light is transmitted through a light-transmissive area (72) of the light guiding plate (60) to be incident on a transparent display area of the liquid crystal panel (20), and therefore, the observer can see a background displayed with high transparency in the transparent display area (76).
