Abstract
A method for producing top-emission organic EL display device, in which, using cover material having flexibility such as resin film, space between organic EL layer-side substrate and cover material is made into decompressed state, thereafter, adhesion properties between organic EL layer-side substrate and cover material is maintained by retaining decompressed state in the space between organic EL layer-side substrate and cover material when adhering organic EL layer-side substrate and cover material by adjusting pressure of space on opposite side to the organic EL layer-side substrate, in relation to cover material so that deterioration in display properties can be restrained by preventing organic layer on auxiliary electrode removed by laser light from being scattered on pixel area. In the method for producing top-emission organic EL display device described above, resin film including barrier property with oxygen permeability of 100 cc/m2·day or less is used as the cover material.
