At least one light-emitting diode emitting a light, and a front panel
provided at a position forward in a traveling direction of the light
emitted from the light-emitting diode, form a display device. In this
display device, the front panel is so shaped as to protrude in the
traveling direction of the light. An embossed portion diffusing the light
emitted from the light-emitting diode is formed on the front panel.
