| description | A spread illuminating apparatus includes an LED, a transparent resin plate and a light reflecting sheet, wherein the transparent resin plate includes slits adapted to have inserted therein flap portions of the light reflecting sheet, and wherein an adhesive tape with flexibility is placed along at least one flap portion of the light reflecting sheet so as to cover at least one slit of the transparent resin plate, whereby the light reflecting sheet is prevented from warping or undulating in spite of difference in thermal expansion coefficient between the materials of the transparent resin plate and the light reflecting sheet, and also whereby light emitted from the LED and traveling in the transparent resin plate is totally reflected by the flap portions and therefore prevented from leaking from the outer side surfaces of the transparent resin plate. |
