A display structure for displaying a display sheet having information marked thereon. The display structure has a substantially concave frame formed by a back wall and a set of frontwardly extending peripheral walls. A peripheral border extends outwardly from the peripheral walls. The frame border is provided with a frame border channel formed therein. A photoluminescent component is adapted to be inserted into the frame border channel. The photoluminescent component is provided with a groove formed therein. The display sheet is adapted to be inserted into the groove formed in the photoluminescent component. A set of lighting tubes is positioned inside the chamber. A reflective sheet is positioned underneath the lighting means so as to reflect the light rays generated by the lighting tubes towards the rear surface of the display sheet. One of the main characteristics of the invention resides in that the configuration of the channel allows the light rays generated by the light source and reflected by the reflective sheet to flow simultaneously towards the back surface of the display sheet and the photoluminescent component. A single light source is thus used to illuminate both the back surface of the display sheet and to generate a photoluminescent reaction in the photoluminescent component which surrounds the display sheet and thus provides a visually attracting border.
