RESIN SHEET PRODUCING METHOD, OPTICAL MEMBER PRODUCED BY RESIN SHEET PRODUCING METHOD, AREA LIGHT SOURCE DEVICE IN WHICH OPTICAL MEMBER IS USED, LIQUID CRYSTAL DISPLAY DEVICE, AND MOBILE DEVICE
摘要:
An area light source device has a transfer-molded optical member, and a light source disposed in a position facing at least one of end faces of the optical member. Light incident to the optical member from the light source is output through a light exit surface of the optical member. A cutting back clearance portion is provided in at least one of corner portions of the end face of the optical member.
