Abstract
A structure for increasing the light-emitting efficiency of a light-emitting device has a substrate with different refractive indexes or scattering surfaces. These features scatter light, which emits from the light-emitting device, so as to increase the chances for the amount of light emitted out of the device. The structure further has a transparent electrode or electrode layer with a plurality of geometric openings. The openings provide paths for the light inside the light-emitting device to directly emit out, so as to avoid the loss resulted from the light passing through the transparent electrode layer. By doing so, the light-emitting efficiency of the light-emitting device increases.
