The light-diffusing sheet stacked body includes a first light-diffusing sheet disposed on the light guide plate, a second light-diffusing sheet disposed on the first light-diffusing sheet, and a third light-diffusing sheet disposed on the second light-diffusing sheet. The first light-diffusing sheet includes first protrusions at an upper surface side thereof. The second light-diffusing sheet includes second protrusions at an upper surface side thereof. The third light-diffusing sheet includes third protrusions at an upper surface side thereof. A shape of the third protrusion may be different from a shape of the first protrusions and/or a shape of the second protrusions.

OPTICAL SHEET, BACKLIGHT UNIT, LIQUID CRYSTAL DISPLAY APPARATUS, AND INFORMATION DEVICE
An optical sheet 5 has an irregular shape on at least a first surface thereof. The first surface has a glare contrast of 4 % or less as measured in accordance with JIS C 1006: 2019. The first surface may have an arithmetic mean roughness Ra of 0.6 μm or less as measured in accordance with JIS B 0601: 2001 (where the evaluation length is set to 290 μm). The first surface may have a peak count RPc of 16 or more as measured in accordance with JIS B 0601: 2001 (where the evaluation length is set to 290 μm).
An optical sheet 43 is built into a liquid crystal display device in which a plurality of light sources 42 are dispersedly provided on the back surface side of a display screen. One surface of the optical sheet 43 has an uneven shape. In a predetermined region R of the one surface of the optical sheet 43, a luminance-enhancing member 25 for enhancing the total light transmittance of the predetermined region R is provided so that recesses 22a in the uneven shape are at least partially filled.
The present invention provides a structure protection sheet, which makes it possible to significantly reduce the work period in the provision of a protection layer on the surface of a structure such as concrete, to protect the structure for a long period, to prevent the occurrence of a blistering phenomenon associated with water vapor in the inside of the concrete, and to prevent the deterioration in adhesiveness. The present invention relates to a structure protection sheet comprising a polymer cement cured layer arranged on a structure side and a resin layer arranged on the polymer cement cured layer, the structure protection sheet being characterized by having a water vapor transmission rate of 10 to 50 g/m2･day.
