OPTICAL ELEMENT LAMINATE, AND MANUFACTURING METHOD THEREFOR, BACKLIGHT AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is an optical element laminate in which the lack of rigidity of an optical element is improved while an increase in the thickness of a liquid crystal display device is suppressed, and the display characteristics of the liquid crystal display device are not degraded. The optical element laminate is provided with a plate-shaped support having a first main surface and a second main surface, and an optical element having the form of a film or a sheet laminated on the first main surface and/or the second main surface of the support. The peripheral edge of the laminated optical element is bonded to at least two opposite edges of the support, and the optical element and the support are tightly bonded. The thickness (t) of the support, the peripheral length (L) of the support, and the tension (F) of the optical element satisfy the relationship 0 = F = 1.65 x 104 x t/L in an environment at a temperature of 70°C.
