BRIGHTNESS-ENHANCED MULTILAYER OPTICAL FILM WITH LOW REFLECTIVITY FOR DISPLAY DEVICE AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a low-reflectivity, brightness-enhanced multilayer optical film for an OLED capable of providing a high brightness characteristic and an anti-reflection function because it is high in emission efficiency from a light-emitting element to the outside of a display device; and to provide an OLED display device equipped with the same.

SOLUTION: This multilayer optical film is so structured that a light diffusion layer containing a resin and spherical particles to diffuse light is formed on any one surface of a transparent substrate; and a light-absorbing layer containing light-absorbing particles of a core-shell structure containing a light-absorbing agent as a core and a transparent resin as a shell and a transparent resin playing a binder role is formed on the light diffusion layer.
