Abstract
Provided is a display device that can prevent light emitted from, a light guide plate from arriving at a display panel via a gap in an optical sheet and a gap between the optical sheet and a holding frame member. The display device is provided with: a light guide plate having a light exit surface; an optical sheet that is arranged facing the light exit surface, that is configured from a plurality of stacked unit sheets, and in which a plurality of flanges are arranged in each of the unit sheets so as to extend along the sheet surface of the unit sheet from the side edge of the unit sheet toward the exterior; and a holding frame member having formed therein a plurality of accommodating sections in which the flanges of the optical sheet are accommodated when holding the optical sheet. One or more of the plurality of flanges in each of the unit sheets is a matching flange having a shape that matches the shape of the accommodating section along the sheet surface. In this way, the accommodating section blocks light from the light guide plate by accommodating one or more of the matching flanges.
