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 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.

An optical film for reducing color shift in an LCD is disposed in front of a liquid crystal panel of the LCD. The optical film includes a background layer, a plurality of engraved lens sections formed in the background layer such that the engraved lens sections are spaced apart from each other, and packed portions, each of the packed portions being disposed inside a respective one of the engraved lens sections. The refractive index of the packed portions is different from that of the background layer. The packed portions are partially packed inside the engraved lens sections. The refractive index of the packed portions is greater than that of the background layer. The background layer and the packed portions are made of transparent polymer resin.

A porous glass substrate for displays and a method of manufacturing the same, with which the optical characteristics of a display such as an organic light-emitting device (OLED) can be improved. The porous glass substrate includes a glass substrate and a porous layer formed in at least one portion of one surface of the glass substrate and extending into the glass substrate, the refractive index of the porous layer being smaller than the refractive index of the glass substrate. The porous layer has a plurality of pores which is formed in the glass substrate such that at least one component of the glass substrate except for silicon dioxide (SiO) is eluted from the glass substrate.

An optical film for reducing color shift and an LCD having the same. The optical film is disposed in front of a display panel of the LCD. The optical film includes a background layer and a plurality of engraved or embossed lens sections formed in the background layer such that they are spaced apart from each other. When light having different colors depending on a viewing angle and a grayscale level is emitted, a portion of the light incident onto the lens sections is diffused, and is thus mixed with another portion of the light passing between adjacent lens sections. The cross-section of the lens sections includes first, second and third sides. The first and second sides face each other and are connected by the third side. The average curvature of the third side is smaller than that of the first side and than that of the second side.

Disclosed are a color compensation multi-layered member for a display apparatus, an optical filter for a display apparatus having the same, and a display apparatus having the same. The color compensation multi-layered member for a display apparatus includes a thin layer having a thickness of about 780 nm or less and a first refractive index; a first thick layer having a greater thickness than the thin layer, being formed on a surface of the thin layer, and having a second refractive index; and a second thick layer having a greater thickness than the thin layer, being formed on another surface of the thin layer, and having a third refractive index.
