Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image display apparatus provided with an electromagnetic wave shielding structure by which electromagnetic interference can be reliably prevented without incurring cost increase and which is not disadvantageous for miniaturization and thinness. SOLUTION: A light reflection sheet 16 provided on a rear surface of a light guide plate 14 of a side light type backlight unit 13 is formed as a two layer sheet formed by laminating a light scattering reflection sheet 16b on a conductive sheet 16a and a cold cathode tube 15a disposed along an end surface of the light guide plate 14 is enclosed by folding an end part of the light reflection sheet 16 in a U shape. A tongue part 16c formed by extending one edge part of the light reflection sheet 16 is taken out to an external part of a frame 17 and interposed between side plates of a light cover case 19 and the frame 17. Thereby, the light reflection sheet 16 is connected to a grounding circuit 20a of an electronic circuit board 20 from the light cover case 19 via a housing case 1 and a spring contact piece 21 and electromagnetic wave shielding of the electronic circuit board 20 is carried out to a liquid crystal display panel 3.
