    Abstract: An electroluminescent device includes a substrate, a first electrode, a patterned pixel define layer, a first color layer, a first connection layer, a second color layer, and a second electrode. The patterned pixel define layer has a first opening. A projected area of the first opening on the substrate is A. The first color layer is located in the first opening and electrically connected to the first electrode. A projected area of the first connection layer on the substrate is B. The second color layer is located between the first connection layer and the second electrode. When a ratio of B to A is r1, light emitted by the electroluminescent device has a first color temperature. When the ratio of B to A is r2, the light emitted by the electroluminescent device has a second color temperature.
