a rectangular sheet located behind the display panel, the sheet having a plurality of holes in a peripheral portion thereof; a light source illuminating the display panel with light from behind the display panel; and a housing accommodating the light source, the housing that has a generally box-like shape having a rectangular opening toward the display panel, and has a plurality of engageable portions arranged along a longitudinal direction in a peripheral portion of the rectangular opening, the plurality of engageable portions capable of engaging respectively with edges of the plurality of holes; wherein the plurality of engageable portions are adjustable in position or orientation so as to contact the edges of the plurality of holes. ## Claims ### Claim 1 A display apparatus, comprising: a rectangular display panel including a screen in front; a rectangular sheet located behind the display panel, the sheet having a plurality of holes in a peripheral portion thereof; a light source illuminating the display panel with light from behind the display panel; and a housing accommodating the light source, the housing that has a generally box-like shape having a rectangular opening toward the display panel, and has a plurality of engageable portions arranged along a longitudinal direction in a peripheral portion of the rectangular opening, the plurality of engageable portions capable of engaging respectively with edges of the plurality of holes; wherein the plurality of engageable portions are adjustable in position or orientation so as to contact the edges of the plurality of holes. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein in a standing state where the plurality of engageable portions are situated upward, the sheet is supported by all the plurality of engageable portions. ### Claim 3 (depends on 1) The display apparatus according to claim 1, wherein the plurality of holes are larger than the plurality of engageable portions. ### Claim 4 (depends on 1) The display apparatus according to claim 1, wherein: the plurality of engageable portions each include a flat plate-like contact portion and a shaft portion vertically provided at one end of a surface of the contact portion; the peripheral portion of the housing has a hole into which the shaft portion is allowed to be fit; and the contact portion is rotatable in a state where the shaft portion is fit into the hole. ### Claim 5 (depends on 4) The display apparatus according to claim 4, wherein: the plurality of engageable portions each include a protruding portion vertically provided at another end of the surface of the contact portion; and the peripheral portion of the housing has a plurality of holes into which the protruding portion is allowed to be fit. ### Claim 6 (depends on 4) The display apparatus according to claim 4, wherein the contact portion has a bullet-like planar shape or a polygonal planar shape. ### Claim 7 (depends on 1) The display apparatus according to claim 1, wherein: the plurality of engageable portions each include a parallelepiped contact portion and an elliptical plate-like contact portion overlapping the support portion in a state where a longer-diameter direction of the contact portion matches a longitudinal direction of the support portion; the plurality of engageable portions each include triangular prism-shaped protruding portions provided at both of two ends of the support portion in the longitudinal direction thereof; and the peripheral portion of the housing includes a plurality of fitting portions into which the support portion and the protruding portions are allowed to fit, the plurality of fitting portions being aligned in a width direction of the peripheral portion of the housing. ### Claim 8 (depends on 1) The display apparatus according to claim 1, further comprising a rectangular light guide plate or diffuser plate outputting light incident thereon from the light source toward a rear surface of the display panel; wherein the sheet is an optical sheet located between the display panel and the light guide plate or the diffuser plate.
