In such a conventional display panel in which light is lit or blinked on the surface,
It is necessary to wire a circuit on the back surface of the display panel, connect a light source such as a light bulb to the conductor of the circuit at each display position by soldering, and fix and support the light source at the display position. Since the work of soldering the light source and the work of supporting and fixing the light source increase the manufacturing cost, it has been conventionally impossible to easily use a display panel that lights or blinks light. Also, because the light source is attached to the display panel by soldering,
There is a risk that the light source may fall, the position of the light source may be displaced, or the connection may be defective.

The present invention has been made in view of this point, and makes it possible to easily and surely fix the light source at the display position and connect the circuit, and significantly reduce the manufacturing cost. An object is to provide a display device.

A light source member comprising an element, two terminals connected to the solid light emitting element, and an adhesive applied to the same one-sided base material as the solid light emitting element, and the solid light emitting element is provided in the through hole of the display panel. The light source member is adhered to the display panel with the adhesive while the two terminals are matched with each other and the two terminals are connected to the pair of conducting wires, and the light is emitted from the solid light emitting element by the switch operation of the switch means. Than it is.

[0006]

The light source member is bonded to the display panel so that the two terminals of the light source member come into contact with the pair of conducting wires provided on the display panel. As a result, the solid state light emitting device is fixed to the display panel. The solid-state light-emitting element is connected to a circuit including a pair of conducting wires, and when the power switch is turned on, the solid-state light-emitting element emits light to illuminate and display.
