摘要： PROBLEM TO BE SOLVED: To provide an internally-illuminated pushbutton switch device that consumes little current by passing and projecting a part of a semitranslucent pushbutton through and from a translucent plate having an EL sheet wound on its outer peripheral end face, and forming a hole that provides edge-light action. SOLUTION: When this internally-illuminated pushbutton switch device is employed in a pushbutton type portable telephone, blue-green light is emitted from the emitting surface of an EL sheet 11 during a call, at the application of a voltage to the sheet 11 wound on the outer peripheral end face of a translucent plate 10, and a part of the light is allowed to pass through the plate 10 and reflected by an edge 10e so that a pushbutton 7 is brightly illuminated from inside by the mixture of the luminous color of the sheet 1 and the phosphor color of the plate 10. The remaining light propagates within the plate 10 while undergoing total reflection, has its brightness condensed by the addition of secondary emission of a dispersedly contained phosphor, and undergoes irregular reflection at an irregularly reflecting surface 10f to brightly illuminate a liquid-crystal display panel 21 from its back. No LEDs and lamps need to be provided on a circuit board 9, so the current consumed is decreased and costs reduced.

摘要： PROBLEM TO BE SOLVED: To restrict the deterioration of a fluorescent pigment so as to obtain the desirable color emission for a long time by forming a light transmitting ultraviolet ray absorbing layer between a light emitting layer and a transparent electrode layer. SOLUTION: An ultraviolet ray absorbing layer 2, a light emitting layer 3 and an insulating layer 4 are laminated in order on a transparent electrode film 1, which is formed by laminating a transparent electrode layer made of ITO on a transparent film 1a. In the ultraviolet ray absorbing layer 2, a mixture of fluororesin, acetic acid - n butylcarbitol and Ce oxide is used as a binder. As the light emitting layer 3, ZnS phosphor, to which Cu is added, is used. The fluorescent pigment is added to the light emitting layer 3, besides the phosphor. As a binder of the light emitting ink, the mixture of acetic acid - n - butylcarbitol is used. The insulating layer 4, which is formed by printing with the insulating ink, is formed on the light emitting layer 3. As the insulating ink, a mixture obtained by mixing barium titanate in the binder, which is obtained by mixing the fluororesin and the acetic acid - n - butylcarbitol, is used. The binder, which contains the fluororesin, and the insulating layer 4 prevent the intrusion of moisture into the light emitting layer 3.
