Abstract:
Provided is a light-emitting apparatus which can prevent a shadow mask from contacting a light-emitting medium to suppress damage of the medium, by using a conductive layer formed on a device isolation layer as a pressing member for the shadow mask, and can attain more secure conduction between a second electrode and an auxiliary electrode. A production method of the light-emitting apparatus includes forming first electrodes and auxiliary electrodes on a substrate; forming a device isolation layer between the first electrodes and forming an opening on each of the first electrodes and the auxiliary electrodes; forming a conductive layer on the device isolation layer so as to cover the openings above the auxiliary electrodes; bringing a shadow mask into contact with the conductive layer and forming a light-emitting medium in a thickness smaller than the thickness of the conductive layer; and forming a second electrode so as to cover the light-emitting medium, the device isolation layer, and the conductive layer.
