Abstract
A display device configured for use as a backlight for a display panel that effects presentation via liquid crystals that produce a monochrome image. The display device includes a light guide plate; and a first and a second light source arranged at an edge of the light guide plate. The light guide plate includes: an emission surface; a cluster of first reflective structures configured to reflect light incident thereon from the first light source thereby changing the optical path of the light and causing the light to exit from the emission surface to serve as the backlight; and a cluster of second reflective structures configured to reflect light incident thereon from a second light source thereby changing the optical path of the light and causing the light to exit from the emission surface to effect a predetermined display.
