Title:
Substrate for organic light emitting element with improved light extraction efficiency, manufacturing method thereof, and organic light emitting element provided with this
Document Type and Number:
Japanese Patent JP6310638
Kind Code:
B2
Abstract:
A substrate for an organic light-emitting device (OLED) with enhanced light extraction efficiency, a method of manufacturing the same and an OLED having the same, in which the light extraction efficiency is enhanced, thereby reducing the phenomenon of color shift in which color changes depending on the position of a viewer within the viewing angle. The transparent substrate used in an OLED includes an anode, an organic light-emitting layer and a cathode which are stacked on each other, the transparent substrate comprising a porous layer pattern in at least one portion of one surface thereof that adjoins the organic light-emitting device, a refractive index of the porous layer being smaller than a refractive index of the transparent substrate, the cross sectional shape of the porous layer pattern being selected from the group consisting of a semi-oval, a trapezoid and a wedge.
