Abstract
A light-emitting display device includes a substrate, several light emitting units for emitting light with different wavelengths, and an optical lens. The substrate has at least one receiver for containing these light emitting units. A light guide structure of the light-emitting display device can be the receiver with a specific designed, a frame body with at least one corresponding through hole formed on the corresponding receiver, or at least one optical element formed on the corresponding receiver, so as the light emitted by the light emitting units can be reflected towards the preset optical axis. And the optical lens is formed on the light guide structure as medium for mixing lights of different wavelengths for achieving a uniform lighting effect.
