Light-Emitting Device and Method for Manufacturing the Same

A method for manufacturing a light-emitting device, comprising the steps of

• forming a separation layer over a substrate;
• forming a semiconductor circuit element layer over the separation layer;
• forming a plurality of first electrodes electrically connected to the semiconductor circuit element layer over the semiconductor circuit element layer;
• forming a partition wall overlapping with an end portion of each of the plurality of first electrodes over the semiconductor circuit element layer, the partition wall extending along a first direction;
• forming an organic material layer emitting red light, an organic material layer emitting green light, and an organic material layer emitting blue light over the respective first electrodes,
• forming a second electrode over the organic material layers to be in contact with the partition wall, and
• separating a stack structure including the semiconductor circuit element layer, the first electrodes, the partition wall, the organic material layers, and the second electrode from the substrate using the separation layer along a second direction perpendicular to the first direction,
• wherein organic material layers emitting light of the same color are arranged adjacent to each other in a line,
• wherein a first region where organic material layers emitting red light are arranged adjacent to each other in a line, a second region where organic material layers emitting green light are arranged adjacent to each other in a line, and a third region where organic material layers emitting blue light are arranged adjacent to each other in a line extend along the first direction, and
• wherein the partition wall exists in a region between the first region and the second region, a region between the second region and the third region, and a region between the third region and the first region.
