SURFACE LIGHT SOURCE DEVICE AND FRAME USED THEREIN

摘要

Light that leaks from an outer peripheral surface of a lightguide plate can be reflected and returned to the lightguide plate by a frame, and light that is transmitted through the frame to leak out can be reduced. A reflecting sheet is disposed in a lower surface of the frame, and the lightguide plate and the light source are accommodated in the frame. The frame is formed such that an outer peripheral surface of a rectangular-frame-shaped inside frame portion made of a white resin is covered with a rectangular-frame-shaped outside frame portion made of a black resin. The inside frame portion and the outside frame portion are integrally molded by a two-color molding method.
