A pixel structure of electroluminescent display panel includes a first organic light-emitting layer, a second organic light-emitting layer and a first color filter pattern. The first organic light-emitting layer is disposed in a first sub-pixel region and a second sub-pixel region. The first organic light-emitting layer includes a first organic light-emitting material for emitting a first primary color light, and a second organic light-emitting material for emitting a second primary color light. The second organic light-emitting layer is disposed in the first sub-pixel region, the second sub-pixel region and a third sub-pixel region. The second organic light-emitting layer includes a third organic light-emitting material for emitting a third primary color light. The first color filter pattern, which allows the first primary color light passing through, is disposed in the first sub-pixel region. The first sub-pixel region and the second sub-pixel region have different cavity lengths. There is no color filter p
