[0005]

[Problems to be solved by the device]

 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, when the light emitting surface is damaged, the light source is replaced with the light source even if it is usable, which is 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 in the vicinity of the base of the light emitting element than in other portions. Also, some of the reflective surfaces in the plastic body are arranged so that they are perpendicular to the axial direction of the solid plastic body. The luminous intensity at the joint with the peripheral part of the solid plastic body also tended to decrease.

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