    Abstract: A method for evaluating a lifespan of an organic light emitting display panel includes: aging an organic light emitting display panel, including first light emitting elements for emitting a first color, second light emitting elements for emitting a second color, and third light emitting elements for emitting a third color, during a preset aging period by displaying the first color in a first pattern area of the organic light emitting display panel and displaying a fourth color in a second pattern area of the organic light emitting display panel; measuring luminances of the first pattern area and the second pattern area by displaying the first color in the first pattern area and the second pattern area during a measurement period; and calculating a lifespan of the first light emitting elements based on the measured luminance of the first pattern area and the measured luminance of the second pattern area.

    Abstract: A method of forming a thin film includes preparing a mixture including a light emitting layer material that forms a light emitting layer and a material that forms a layer adjacent to the light emitting layer, and sequentially laminating the light emitting layer and the layer adjacent to the light emitting layer onto a substrate inside a chamber by heating the mixture to a process temperature of the light emitting layer material and a process temperature of the additional material. The light emitting layer material and the additional material have process temperatures that are different from each other. The light emitting layer material and the additional material are laminated onto the substrate sequentially from one of the light emitting layer material and the additional material having a lower process temperature to one of the light emitting layer material and the additional material having a higher process temperature.

    Abstract: A deposition device according to an embodiment includes a first deposition source, a second deposition source, and a third deposition source arranged sequentially in a first direction, a first angle limitation plate disposed outside of the first deposition source, a second angle limitation plate disposed between the first deposition source and the second deposition source, a third angle limitation plate disposed between the second deposition source and the third deposition source, and a fourth angle limitation plate disposed outside the third deposition source. A deposition material of the first deposition source and a deposition material of the third deposition source include a same dopant material. A deposition material of the second deposition source includes a host material.
