Abstract
A manufacturing method of a light emitting diode device and a light emitting diode device are provided. The manufacturing method of the light emitting diode device includes: forming a light emitting lamination layer on a base substrate, the light emitting lamination layer including a first semiconductor layer, a first light emitting layer, a second semiconductor layer, a second light emitting layer and a third semiconductor layer sequentially formed on the base substrate; dividing the light emitting lamination layer to form a plurality of light emitting units spaced from each other, each light emitting unit including a first area and a second area spaced from each other; and removing the third semiconductor layer and the second light emitting layer in the first area to form a first sub light emitting unit, and the second area being used for forming a second sub light emitting unit.
