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.

Claim (Index 1):
A display apparatus, comprising:\n a light guide plate having a light output surface; an optical sheet including a plurality of unit sheets provided in a stacked manner, the plurality of unit sheets each including a plurality of flanges extending outward from a side edge of the unit sheet along a sheet plane of the unit sheet, the optical sheet facing the light output surface; and a holding frame member including a plurality of accommodation portions formed therein, the plurality of accommodation portions accommodating the flanges included in the optical sheet in a state where the holding frame member holds the optical sheet, wherein at least one of the plurality of flanges of each of the plurality of unit sheets is a matching flange having a shape matched to a shape of the corresponding accommodation portion along the sheet plane, wherein, in each of the accommodation portions, at least one of the matching portions included in the optical sheet is accommodated, wherein each of the flanges has a through-hole formed therein, the through-hole running through the flange, wherein an engageable protrusion to engage with the through-hole is formed in each of the accommodation portions, wherein the through-hole in the matching flange has a cross-sectional shape along the sheet plane, matched to a cross-sectional shape of the engageable protrusion along the sheet plane, wherein the plurality of unit sheets are rectangular, wherein the plurality of flanges extend from a specific end side of each of the unit sheets, and wherein in the case where the plurality of flanges all have the same length in a direction in which the plurality of flanges extend, the matching flange has a longest length in a direction along the specific end side among lengths of the plurality of flanges in the direction along the specific end side.
