A trans-reflective organic electroluminescent panel comprises a substrate, several controlling components and displaying regions formed on the substrate. The displaying regions are electrically connected to the controlling components, and each display region has a trans-reflective organic electroluminescent device (OELD). The trans-reflective OELD at least comprises a transparent electrode formed on the substrate, a light emitting layer formed above the transparent electrode, a reflective electrode formed above the light emitting layer and a semi-reflecting layer. Light generated from the light emitting layer emits toward the transparent electrode to form a light path, and the semi-reflecting layer is disposed in the middle of the light path. Also, a proper proportion of the area of the semi-reflecting layer to the area of the transparent electrode is determined for improving the luminescence and color performances of the trans-reflective organic electroluminescent panel.
