PURPOSE: A reflection sheet is provided to demonstrate more excellent visibility in case there is a light source; and express the printed contents precisely without deformation. CONSTITUTION: A reflection sheet which is reflected from behind comprises a print sheet(10) which is composed in a plastic sheet phase capable of printing on the surface and penetrating the light; a refractive element(11) which makes a light, which penetrated the print sheet, to be refracted on the other surface of the print sheet; and a reflection sheet(20) is laminated to return the light refracted by the refractive element penetrating the print sheet while being positioned in the back of the refractive element to the surface of the print sheet. The lamination of the surface on which the refractive element of the print sheet is formed and the reflective sheet makes an apex(11a) of the refractive element formed on the other side of the print sheet laminating the print sheet to be adhered to an adhesion layer(21). The refractive element is processed in a triangular shape with a straight line side(110) or in a semi-circle shape with a curved side(120). The size of the dot shape ranges from 0.1- 1 millimeter and the interval of the dot ranges from 0.3 to 2.5 millimeter if possible. The arrangement of the dot shape is formed in a radial shape which maintains the same length of X axis and Y axis. |
