Problems solved by technology

[0004] On the other hand, organic light-emitting display devices have disadvantages in that light is not emitted forward but sideways due to internal reflection, resulting in a decrease in light extraction efficiency, and color shift occurs due to changes in viewing angles due to element structures.
[0006] However, the use of a diffusion layer containing particles of a specific size can reduce total reflection and suppress color shift, but it will lead to a reduction in the front brightness of the display device

Abstract

The present invention relates to an optical member and a display device having the same, and the optical member comprises: a first plane; a second plane facing the first plane; and a material layer formed between the first plane and the second plane, wherein the material layer has a penetration area through which light penetrates and a plurality of scattering areas in which the light is scattered,and the plurality of scattering areas are arranged by being spaced from each other in the planar direction and include a plurality of scattering particles therein. Therefore, the present invention can improve light extraction efficiency while minimizing a reduction in the frontal brightness of a display device, and can alleviate a color shift phenomenon.

Description

technical field [0001] The present invention relates to an optical element and a display device including the same, in particular to an optical element capable of improving light extraction efficiency and color shift and a display device including the same. Background technique [0002] In recent years, Flat Panel Displays have attracted worldwide attention. The flat panel display device includes a liquid crystal display device (Liquid Crystal Display), a plasma display device (Plasma Display Panel), an organic light emitting display device (Organic Light Emitting Device) and the like. [0003] Among them, the organic light-emitting display device has a wide viewing angle and a fast response speed, and can realize high-quality display images. In particular, an organic light-emitting display device with a microcavity structure can utilize the optical resonance effect between the upper and lower electrodes to increase output efficiency and improve light color purity. Such an...
