Abstract: PURPOSE:To obtain uniform panel light emission. CONSTITUTION:A cold cathode ray tube is disposed as a line light source 2 on one side face of a transparent light transmission plate 1 made of an acrylic resin and an aluminum sheet printed white is disposed as a side face reflection plate on the other side face. Dotty light diffusive transmission parts 3 are printed and formed on the rear surface of the light transmission plate in such a manner that the area rate thereof is gradually larger the furtherer from the line light source 2 up to the prescribed point between the line light source 2 and the side face reflection plate 4 and the area rate is gradually smaller the nearer the side face reflection plate from the prescribed point. The light diffusive transmission parts 3 are so printed and formed near the line light source 2 that the area rate of the light diffusive transmission parts 3 is gradually larger the nearer the end of the line light source 2 from the central part of the line light source 2.

Abstract: PURPOSE:To substantially prevent the generation of clogging of a plate and defect such as ink thinning and to stabilize the quality at the time of mass production by providing a diffuse transmission parts with patterns of 20 to 29 line density. CONSTITUTION:The diffuse transmission parts 5 of such gradation to gradually increase the areas thereof the further from a light source 1 are formed on the area surface of a transparent light transmission part 2. The light arriving from a light source 1 at the diffuse transmission parts 5 diffuses there and heads further in the multiple directions of the transparent light transmission part 2 such as the directions apart from the light source 1. The diffuse transmission parts 5 are formed by confining the density to

Abstract: PURPOSE:To omit a process concerning welding and lamination with a double- side tape by providing a transparent pattern adhesive layer the area of which gradually increases as it recedes in the distance from a light source between a transparent light leading plate and a white scattering reflecting plate. CONSTITUTION:A transparent adhesive layer 5 the area of which gradually increases as it recedes in the distance from a light source 1 is provided between a transparent light leading plate 2 and a white scattering reflecting plate 4. The pattern of the transparent pattern adhesive layer 5 is circular, and its area is changed by changing the measurement of its diameter. The transparent pattern adhesive layer 5 is formed by a printing method or a transcription method such as a gravure printing, an offset printing or a screen printing of a pressure sensitive adhesive made of polyester, transparent acrylic, vinyl and other resin as its main component. In this case, there is no process of welding and others, and it is possible to prevent deterioration of quality without causing flaws.

Abstract: PURPOSE:To obtain an edge light system plane emitter without generating loss of light and with high luminance. CONSTITUTION:Film in which silver vapor-deposition is applied to polyethylene terephthalate film is used as silver vapor-deposited film 4, and the silver vapor- deposited film 4 is adhered closely setting a vapor-depositing plane at the inside on an aluminum plate with a pressure sensitive adhesive double coated tape, and after that, molding working is performed setting the silver vapor-deposited film 4 at the inside, and a light source covering plate 3 whose surface is covered with the silver vapor-deposited film 4 closely can be manufactured. Thence, the edge light system plane emitter can be obtained by fitting the light source covering plate 3 in the side terminal part of a transference light conduction plate 1 so as to cover a light source 2 arranged at the side plane of the transference light conduction plate 1.
