Title:
REFLECTOR
Document Type and Number:
Japanese Patent JP2004009591
Kind Code:
A
Abstract:
To provide a reflector having a reflection ratio necessary for back light of brightness and of high reliability and light fastness.
A light diffusion layer (B) is formed on a polymer film (A). When the layer (A), layer (B), an underlying layer (C), a reflective layer (D) mainly containing silver, and a protective layer (E) are laminated in turn, (1) the reflective layer (D) is subjected to vacuum vapor deposition under a pressure of 13.3 mPa or below, or (2) the layer (D) is subjected to spatter deposition under a pressure of 20 mPs or below, preferably 7-0.1 mPa, to obtain the reflector. The obtained reflector is installed on the lower surface of the photo-conductive board of the back light with its reflecting surface turned upward.
