Abstract
A display device includes a substrate, a plurality of light-emitting elements on the substrate, a bank portion surrounding the plurality of light-emitting elements, a sealing layer, and a dummy pattern. The sealing layer includes an organic material and covers the plurality of light-emitting elements. The dummy pattern is located between the sealing layer and the substrate and on a side opposite to the plurality of light-emitting elements with respect to the bank portion. The sealing layer has optical transparency, and the dummy pattern has light reflectivity.
Claims18
A display device comprising:
- a substrate;
- a plurality of light-emitting elements formed on the substrate;
- a bank portion formed on the substrate and surrounding the plurality of light-emitting elements;
- a light-transmissive sealing layer including an organic material and covering the plurality of light-emitting elements;
- and
- a dummy pattern having light reflectivity between the sealing layer and the substrate and on a side opposite to the plurality of light-emitting elements with respect to the bank portion.
A manufacturing method of a display device comprising:
- preparing a substrate;
- forming a dummy pattern having light reflectivity on the substrate;
- after the dummy pattern is formed, forming a plurality of light-emitting elements on the substrate and forming a bank portion surrounding the plurality of light-emitting elements;
- and
- after the plurality of light-emitting elements and the bank portion are formed, forming a light-transmissive sealing layer covering the light-emitting elements,
- wherein the forming the sealing layer includes applying an organic material.
