[0122] Figure 20 The cross-sectional configuration of the display area 110 in the display according to the second embodiment of the present invention is shown. This display has the same configuration as that of the first embodiment except that the optical functional film 20 is disposed on the adhesive layer 40 side of the sealing panel 30 . Therefore, in the following description, the same components are denoted by the same reference numerals as those of the first embodiment.

Abstract

There are provided an optically-functional film allowed to prevent peeling due to adhesion failure or deterioration due to moisture diffusion and a method of manufacturing the same, and a display allowed to prevent a decline in luminance and a color change depending on a viewing angle and a method of manufacturing the same. The optically-functional film includes: an intermediate layer, made of an insulating material including silicon, and having silicon-containing particles therein or on a top surface thereof; and an outermost layer made of the same material as that of the intermediate layer, whereas having a density higher than that of the intermediate layer, and having a bottom surface in contact with a top surface of the intermediate layer and a top surface with asperities.

Description

technical field [0001] The present invention relates to an optical functional film suitable as a scattering film for improving the image quality of a display, etc., and a manufacturing method thereof. In addition, the present invention also relates to a display including the optical functional film and a manufacturing method thereof. Background technique [0002] An example of a display using a self-luminescent element is a display using an organic light-emitting element (organic EL (electroluminescent) element). However, in related art displays, high directivity of EL light emission causes a decrease in luminance depending on a viewing angle, thereby causing color variations such as color imbalance. Therefore, for example, as described in Japanese Laid-Open No. 2008-515129 of PCT International Application, there is proposed an adhesive including a scatterer added between a protective film placed over the surface of an organic light-emitting element and an opposite substrat...
