PURPOSE: A light emitting device for a banner advertisement sheet using side illumination is provided to arrange luminous elements at right and left side, thereby enabling uniform illumination by scattering from light collision. CONSTITUTION: A supporting plate(10) has a proper area to stably support side plates(20). Side plates(20) are installed to stand erect at both side ends of the supporting plate and arranged with proper width and height considering a banner advertisement sheet. Each side plate has light emitting elements inside. An upper plate(30) connects side plates fixed to the supporting plate with each other at the top for preventing the side plates from being parted or warped for draping or fixing an advertisement sheet. |
