LIGHT CONTROL LAYER OF BACKLIGHT, BACKLIGHT, LIQUID CRYSTAL DISPLAY, AND METHOD OF MANUFACTURING LIGHT CONTROL LAYER OF BACKLIGHT

摘要

A light control layer (30) comprises at least two optical sheets (a polarization reflective layer (40) and a diffusion plate (32)) laminated with an adhesive layer (60) interposed therebetween.The adhesive layer (60) is provided with portions (A) having a refraction factor lower than that of two optical sheets (the polarization reflective layer (40) and the diffusion plate (32)) to which the adhesive layer (60) is adhered.
