REFLECTOR, METHOD FOR MANUFACTURING REFLECTOR, AND BACKLIGHT PANEL

摘要

A reflector (5) is a porous body having fine cells (7) that are closed cells, and is formed of, for example, a resin foam body. A plurality of protrusions (11) is formed on the surface of the reflector (5). That is, a light guide plate (3) comes into contact with the protrusions (11) on the surface of the reflector (5), thereby forming a gap due to the protrusions (11) between the light guide plate (3) and the reflector (5). The portion of the protrusion (11) above the base portion thereof is defined as a protrusion area, and the portion below the base portion of the protrusion (11) is defined as an area other than the protrusion area. According to the present invention, the degree of hardness in the protrusion area of the reflector (5) is required to be 95 or more on the durometer A scale. If the degree of hardness on the durometer A scale is less than 95, white spots are highly likely to appear.
