LIGHT CONTROL LAYER OF BACKLIGHT, BACKLIGHT, LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD FOR PRODUCING LIGHT CONTROL LAYER OF BACKLIGHT

摘要

A light control layer (30) includes an adhesive layer (60); and at least two optical sheets (a reflective polarizer layer (40) and a diffuser layer (32)) stacked so as to sandwich the adhesive layer (60). The adhesive layer (60) includes a low reflectance section A having a reflectance lower than a reflectance of each of two optical sheets (a reflective polarizer layer (40) and a diffuser layer (32)) which are firmly fixed to each other by the adhesive layer (60).
