Abstract
A display device includes an operation screen attached to an apparatus to accept instructions for the apparatus, display lamps each including a light emitter to provide notification of a state of the apparatus, a light source to emit light, a substrate on which the light source is mounted, a lens that makes up the light emitter of each one of the display lamps, a light guide to guide the light emitted from the light source to the lens, and a housing that covers the substrate. In the display device, the housing has an opening at which the lens is exposed, at an area including a corner formed by an edge of a top face on which the operation screen is disposed and a side face. In the display device, the lens and the light guide is coupled to each other at a coupling surface, and the coupling surface is orthogonal.
