DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glossy sheet which can be recognized well when viewed from either side, when one side receives light, and a double-sided display panel using the same. .

[0002]

2. Description of the Related Art Conventionally, a character, a symbol, or a figure is represented by arranging an arc tube in a frame, and the arc tube is energized to emit light, so that the display panel can be used at night or in a dark place. Illuminated signs have been widely used so that characters and the like can be recognized by being illuminated when viewed from either side of the front and back.

[0003]

The above-mentioned conventional illuminated signboard requires a special technique for manufacturing due to its structure, so it has to be ordered from a specialized trader, which is costly. for that reason,
For example, it is not suitable for temporary use such as changing the content every season. In addition, there is a limit in expressing fine characters and the like due to bending and piping of the arc tube.

According to the present invention, a character or the like is drawn on a plate having a light-transmitting property with a fluorescent pigment or a fluorescent pigment, and when the light is illuminated from the plate, the character or the like is seen well from both sides of the plate. It is an object of the present invention to provide a glitter sheet and a double-sided display panel for freely expressing characters and the like shining on both sides at a simple and inexpensive cost by focusing on shining.

[0005]

In order to solve the above-mentioned problems, the glittering sheet according to claim 1 is obtained by printing a light-transmitting pigment or a fluorescent pigment or a pigment containing the same on one surface of a light-transmitting base sheet. And a light-transmitting adhesive layer is formed on the other surface of the base sheet with an adhesive, and a release paper is attached thereon.

When the release paper is peeled off from the glittering sheet and attached to a plate having light transmissivity, and light is applied to the end surface of the outer edge of the plate, the light is scattered inside the plate. , Hit the pigment layer through the adhesive layer and the base sheet of the glittering sheet,
Since a part transmits here and a part reflects here, the glittering sheet shines well when viewed from either side of the front and back of the plate. In this case, if the pigment layer is printed in a shape such as a character, the character shines. When the pigment layer is printed in solid, if the glittering sheet is cut into desired characters or the like and then attached to a plate-like body, the characters or the like shine.

The glittering sheet according to the second aspect of the present invention is characterized in that a pigment layer is formed by printing a luminescent pigment or a fluorescent pigment or a pigment containing the same on both sides of a base sheet having a light transmitting property. In addition, a light-transmitting pressure-sensitive adhesive layer is formed with a pressure-sensitive adhesive, and release paper is attached thereon.

When the release paper is peeled off from the glittering sheet and attached to a plate having a light transmitting property, and light is applied to the end surface of the outer edge of the plate, the light is scattered inside the plate. Then, it passes through the adhesive layer of the glittering sheet and hits the pigment layer, a part of which passes here and a part of which reflects. The transmitted light further passes through the base sheet and strikes another pigment layer, some of which are transmitted and some of which are reflected here. For this reason, the glittering sheet shines well when viewed from either side of the front and back of the plate. In this case, if the pigment layer is printed in a shape such as a character, the character shines. When the pigment layer is printed in solid, if the glittering sheet is cut into desired characters or the like and then attached to a plate-like body, the characters or the like shine.

A double-sided display panel according to a third aspect of the present invention is a plate-like body having a light-transmitting property.
It is characterized in that the release paper is peeled off and adhered, and light is applied to the end face of the outer edge of the plate-shaped body.

In the double-sided display panel using the glittering sheet according to the first aspect, when light is applied to the end face of the outer edge of the plate-like body, the light is scattered inside the plate-like body, and the adhesive layer of the glittering sheet and the base are formed. Since the sheet passes through the sheet and hits the pigment layer, a part of the sheet passes therethrough and a part of the sheet reflects, the glittering sheet shines well when viewed from either side of the front and back surfaces of the plate. In the double-sided display panel using the glittering sheet according to claim 2, when light is applied to the end face of the outer edge of the plate-like body, the light is scattered inside the plate-like body, passes through the adhesive layer of the glittering sheet, and becomes a pigment. It strikes the layer, some transmitting here and some reflecting here. The transmitted light further passes through the base sheet and strikes another pigment layer, some of which are transmitted and some of which are reflected here. For this reason, the glittering sheet shines well when viewed from either side of the front and back of the plate. In this case, when the pigment layer is printed in the shape of a character or the like, the character or the like shines. Also,
When the pigment layer is solid-printed and the glitter sheet is cut into desired characters and the like and then attached to a plate-like body, the characters and the like shine.
