Beschreibung
Zusammenfassung:	There is provided an optical laminate, which has high brightness, is suppressed in brightness unevenness, and is excellent in strength as an integrated product. An optical laminate according to an embodiment of the present invention comprises: a light guide plate; an adhesion layer; and an optical member laminated on the light guide plate via the adhesion layer. The adhesion layer is formed in a dot pattern in plan view, and a density of the dots has such a gradient as to increase from a light-entering side of the light guide plate along a light-guiding direction thereof. In the optical laminate, low-refractive index reinforcing portions are arranged in both end portions of the light guide plate along the light-guiding direction.
