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.
