A method of fabricating a display device includes: preparing a substrate including emission areas and a non-emission area between the emission areas; forming a bank on the non-emission area to a first height; forming light conversion patterns on the emission areas to a height equal to or less than the first height; polishing a surface of a light conversion layer including the bank and the light conversion patterns so that the surface of the light conversion layer is flat; and forming a filler layer on a surface of the substrate on which the light conversion layer is provided. The polishing of the light conversion layer includes planarizing the surface of the light conversion layer so that the bank and the light conversion patterns have a second height through chemical mechanical polishing utilizing a metallic slurry.

The present invention relates to stem cells in which a gene that activates signaling is introduced and to a method for proliferating the stem cells. More specifically, the invention relates to a method of significantly increasing the ability of stem cells to proliferate, either by transfecting stem cells with the Notch intracellular domain (NICD) to activate the Notch signaling pathway, or by transfecting stem cells with the c-MET gene and treating the transfected stem cells with the HGF ligand protein to activate the c-MET/HGF signaling pathway. According to the present invention, as a result of activating the Notch signaling pathway or the c-MET/HGF signaling pathway, stem cells having an excellent ability to proliferate can be produced in large amounts. Particularly, since neural stem cells which have been difficult to culture in vitro can be proliferated in large amounts, thus the neural stem cells will be more useful for the preparation of cell therapeutic agents for treating cranial nerve diseases.
