In a reflection-sheet structure of a backlight unit comprising a light source, a light-guide panel, a diffusion sheet, and a light-collecting sheet part, the reflection-sheet structure being provided on the bottom of the light-guide panel, the present invention provides a reflection-sheet structure provided with a total reflection structure, comprising: a structure sheet of a flat-panel form which supports the whole structure; a transmittance sheet which is laminated on the top of the structure sheet, and is formed to enable light to be transmitted; and a total reflection structure in which a plurality of units are continuously provided between the structure sheet and the transmittance sheet along the lower surface of the transmittance sheet, which has a slope, and of which the cross-sectional area is gradually reduced toward the lower direction thereof so that the light transmitted from the light source is reflected by the slope in order to be transmitted to the top. |
