[0005]

However, the above-described light emitting display device still has the following problems to be solved.

That is, in the above-described light emitting display device, since the light source is embedded in the solid plastic body, if the light source fails, it is necessary to integrally replace each plastic body.

Further, if the light emitting surface is damaged, the light source must be replaced even if it is usable.
It was uneconomical in terms of maintenance.

Further, when the light emitting element is embedded in a curved solid plastic body, for example, one formed in a ring shape, the luminous intensity tends to be lower near the base portion of the light emitting element than in other portions, and Since a part of the reflecting surface to be arranged in the plastic body is arranged so that the surface is perpendicular to the axial direction of the solid plastic body, the side of the reflecting surface and the ring-shaped solid body are arranged. The luminous intensity of the joint portion with the peripheral portion of the plastic body also tended to decrease.

Therefore, an object of the present invention is to provide a light emitting display device which can solve the above problems.
