Abstract
An optical display structure is provided, including a basing layer, a lighting source layer and a capping layer. The basing layer includes a substrate and at least one trace configuration layer. The lighting source layer is disposed on the basing layer at d emits a plurality of lights for providing a light source. The capping layer is disposed above the lighting source layer to seal the optical display structure. An upper light shielding layer is alternatively disposed on the lighting source layer to shield cross-talk interferences of the emitted lights. A lower light shielding layer is alternatively disposed below the basing layer to shield reflected light from the back side of the substrate. Preferably, both the upper and lower light shielding layers can be disposed at the same time to shield cross-talk interferences and reflected light for providing an optimized inventive effect of the present invention.
