Abstract

A right side portion, which is a light emitting device, comprises a side light guide plate and a front light guide plate as a plurality of light guide plates in which light is reflected by a prism and emitted from a light emitting surface. The side light guide plate and the front light guide plate are disposed in a row in a state in which the angles of the light emitting surfaces differ between adjacent light guide plates and the ends of adjacent light guide plates are butted against each other. An LED board is disposed at the end of the side light guide plate, and the end surface of one of the ends of the side light guide plate and the front light guide plate that are abutted against each other is formed as an inclined surface with a reflection function that changes the angle at which the light is guided and causes the light to be incident on the adjacent light guide plate.
